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 branch '00.00-inst' of git://github.com/skeggsb/linux into drm-next

Ben wrote:
The problem is that GA100 added enough new engine types and instances
that we would have begun to overflow various u64 bitfields used to
track the connections between various engines.

Rather than addressing subdevs by a unique index, we give
each subdev a type and instance id, and replace the use of bitfields
tied to subdev index with other methods.

Notable changes:
- replace subdev index with subdev type + instance id
- engines that turn out to be fused-off (can't detect until later in
init) no longer leave dangling pointers around
- new subdev/instance additions no longer need to be made in multiple places
- ampere engine topology is now being parsed

Merge tag 'overflow-v4.18-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull overflow updates from Kees Cook:
"This adds the new overflow checking helpers and adds them to the
2-factor argument allocators. And this adds the saturating size
helpers and does a treewide replacement for the struct_size() usage.
Additionally this adds the overflow testing modules to make sure
everything works.

I'm still working on the treewide replacements for allocators with
"simple" multiplied arguments:

*alloc(a * b, ...) -> *alloc_array(a, b, ...)

and

*zalloc(a * b, ...) -> *calloc(a, b, ...)

as well as the more complex cases, but that's separable from this
portion of the series. I expect to have the rest sent before -rc1
closes; there are a lot of messy cases to clean up.

Summary:

- Introduce arithmetic overflow test helper functions (Rasmus)

- Use overflow helpers in 2-factor allocators (Kees, Rasmus)

- Introduce overflow test module (Rasmus, Kees)

- Introduce saturating size helper functions (Matthew, Kees)

- Treewide use of struct_size() for allocators (Kees)"

treewide: Use struct_size() for kmalloc()-family

One of the more common cases of allocation size calculations is finding
the size of a structure that has a zero-sized array at the end, along
with memory for some number of elements for that array. For example:

struct foo {
int stuff;
void *entry[];
};

instance = kmalloc(sizeof(struct foo) + sizeof(void *) * count, GFP_KERNEL);

Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:

instance = kmalloc(struct_size(instance, entry, count), GFP_KERNEL);

This patch makes the changes for kmalloc()-family (and kvmalloc()-family)
uses. It was done via automatic conversion with manual review for the
"CHECKME" non-standard cases noted below, using the following Coccinelle
script:

// pkey_cache = kmalloc(sizeof *pkey_cache + tprops->pkey_tbl_len *
// sizeof *pkey_cache->table, GFP_KERNEL);
