ALSA/ASoC/SOF/SoundWire: fix Kconfig issues

In January, Intel kbuild bot and Arnd Bergmann reported multiple
issues with randconfig. This patchset builds on Arnd's suggestions to

a) expose ACPI and PCI devices in separate modules, while sof-acpi-dev
and sof-pci-dev become helpers. This will result in minor changes
required for developers/testers, i.e. modprobe snd-sof-pci will no
longer result in a probe. The SOF CI was already updated to deal with
this module dependency change and introduction of new modules.

b) Fix SOF/SoundWire/DSP_config dependencies by moving the code
required to detect SoundWire presence in ACPI tables to sound/hda.

Merge tag 'perf-tools-for-v5.12-2020-02-19' of git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux

Pull perf tool updates from Arnaldo Carvalho de Melo:
"New features:

- Support instruction latency in 'perf report', with both memory
latency (weight) and instruction latency information, users can
locate expensive load instructions and understand time spent in
different stages.

- Extend 'perf c2c' to display the number of loads which were blocked
by data or address conflict.

- Add 'perf stat' support for L2 topdown events in systems such as
Intel's Sapphire rapids server.

- Add support for PERF_SAMPLE_CODE_PAGE_SIZE in various tools, as a
sort key, for instance:

perf report --stdio --sort=comm,symbol,code_page_size

- New 'perf daemon' command to run long running sessions while
providing a way to control the enablement of events without
restarting a traditional 'perf record' session.

- Enable counting events for BPF programs in 'perf stat' just like
for other targets (tid, cgroup, cpu, etc), e.g.:

# perf stat -e ref-cycles,cycles -b 254 -I 1000
1.487903822 115,200 ref-cycles
1.487903822 86,012 cycles
2.489147029 80,560 ref-cycles
2.489147029 73,784 cycles
^C

The example above counts 'cycles' and 'ref-cycles' of BPF program
of id 254. It is similar to bpftool-prog-profile command, but more
flexible.

- Support the new layout for PERF_RECORD_MMAP2 to carry the DSO
build-id using infrastructure generalised from the eBPF subsystem,
removing the need for traversing the perf.data file to collect
build-ids at the end of 'perf record' sessions and helping with
long running sessions where binaries can get replaced in updates,
leading to possible mis-resolution of symbols.

- Support filtering by hex address in 'perf script'.

- Support DSO filter in 'perf script', like in other perf tools.

- Add namespaces support to 'perf inject'

- Add support for SDT (Dtrace Style Markers) events on ARM64.

perf record:

- Fix handling of eventfd() when draining a buffer in 'perf record'.

- Improvements to the generation of metadata events for pre-existing
threads (mmaps, comm, etc), speeding up the work done at the start
of system wide or per CPU 'perf record' sessions.

Hardware tracing:

- Initial support for tracing KVM with Intel PT.

- Intel PT fixes for IPC

- Support Intel PT PSB (synchronization packets) events.

- Automatically group aux-output events to overcome --filter syntax.

- Enable PERF_SAMPLE_DATA_SRC on ARMs SPE.

- Update ARM's CoreSight hardware tracing OpenCSD library to v1.0.0.

perf annotate TUI:

- Fix handling of 'k' ("show line number") hotkey

- Fix jump parsing for C++ code.

perf probe:

- Add protection to avoid endless loop.

cgroups:

- Avoid reading cgroup mountpoint multiple times, caching it.

- Fix handling of cgroup v1/v2 in mixed hierarchy.

Symbol resolving:

- Add OCaml symbol demangling.

- Further fixes for handling PE executables when using perf with Wine
and .exe/.dll files.

- Fix 'perf unwind' DSO handling.

- Resolve symbols against debug file first, to deal with artifacts
related to LTO.

- Fix gap between kernel end and module start on powerpc.

Reporting tools:

- The DSO filter shouldn't show samples in unresolved maps.

- Improve debuginfod support in various tools.

build ids:

- Fix 16-byte build ids in 'perf buildid-cache', add a 'perf test'
entry for that case.

perf test:

- Support for PERF_SAMPLE_WEIGHT_STRUCT.

- Add test case for PERF_SAMPLE_CODE_PAGE_SIZE.

- Shell based tests for 'perf daemon's commands ('start', 'stop,
'reconfig', 'list', etc).

- ARM cs-etm 'perf test' fixes.

- Add parse-metric memory bandwidth testcase.

Compiler related:

- Fix 'perf probe' kretprobe issue caused by gcc 11 bug when used
with -fpatchable-function-entry.

- Fix ARM64 build with gcc 11's -Wformat-overflow.

- Fix unaligned access in sample parsing test.

- Fix printf conversion specifier for IP addresses on arm64, s390 and
powerpc.

Arch specific:

- Support exposing Performance Monitor Counter SPRs as part of
extended regs on powerpc.

- Add JSON 'perf stat' metrics for ARM64's imx8mp, imx8mq and imx8mn
DDR, fix imx8mm ones.

- Fix common and uarch events for ARM64's A76 and Ampere eMag"

perf daemon: Add daemon command

Add a daemon skeleton with a minimal base (non) functionality, covering
various setup in start command.

Add an initial perf-daemon.txt with basic info.

This is in response to pople asking for the possibility to be able run
record long running sessions on the background.

The patchset that starts with this adds support to configure and run
record sessions on background via new 'perf daemon' command.

This is useful for being able to use perf as a flight recorder that one
can interact with asking for events to be enabled or disabled, added or
removed, etc.

ASoC: Fixes for v5.1

A few core fixes along with the driver specific ones, mainly fixing
small issues that only affect x86 platforms for various reasons (their
unusual machine enumeration mechanisms mainly, plus a fix for error
handling in topology).

There's some of the driver fixes that look larger than they are, like
the hdmi-codec changes which resulted in an indentation change, and most
of the other large changes are for new drivers like the STM32 changes.
