HID: initial BPF implementation

Declare an entry point that can use fmod_ret BPF programs, and
also an API to access and change the incoming data.

A simpler implementation would consist in just calling
hid_bpf_device_event() for any incoming event and let users deal
with the fact that they will be called for any event of any device.

The goal of HID-BPF is to partially replace drivers, so this situation
can be problematic because we might have programs which will step on
each other toes.

For that, we add a new API hid_bpf_attach_prog() that can be called
from a syscall and we manually deal with a jump table in hid-bpf.

Whenever we add a program to the jump table (in other words, when we
attach a program to a HID device), we keep the number of time we added
this program in the jump table so we can release it whenever there are
no other users.

HID devices have an RCU protected list of available programs in the
jump table, and those programs are called one after the other thanks
to bpf_tail_call().

To achieve the detection of users losing their fds on the programs we
attached, we add 2 tracing facilities on bpf_prog_release() (for when
a fd is closed) and bpf_free_inode() (for when a pinned program gets
unpinned).

hid: topre: Add driver fixing report descriptor

The Topre REALFORCE R2 firmware incorrectly reports that interface
descriptor number 1, input report descriptor 2's events are array events
rather than variable events. That particular report descriptor is used
to report keypresses when there are more than 6 keys held at a time.
This bug prevents events from this interface from being registered
properly, so only 6 keypresses (from a different interface) can be
registered at once, rather than full n-key rollover.

This commit fixes the bug by setting the correct value in a report_fixup
function.

The original bug report can be found here:

Commit c49c33637802 ("HID: support for initialization of some Thrustmaster

Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:

HID_TMINIT
Referencing files: drivers/hid/Makefile, drivers/hid/hid-quirks.c

Following the discussion (see Link), CONFIG_HID_THRUSTMASTER is the
intended config for CONFIG_HID_TMINIT and the file hid-tminit.c was
actually added as hid-thrustmaster.c.

So, clean up Makefile and adapt quirks to that refactoring.

HID: semitek: new driver for GK6X series keyboards

A number of USB keyboards, using the Semitek firmware, are capable of
handling arbitrary N-key rollover, but due to a buggy report
descriptor, keys beyond the sixth cannot be detected by the generic
HID driver.

There are numerous hardware variants sold by several vendors, mostly
using generic names like "GK61" for the 61-key version. These
keyboards are sometimes known collectively as the "GK6X" series.

The keyboard has three USB interfaces. Interface 0 uses the standard
HID boot protocol, limited to eight modifier keys and six normal keys;
interface 2 uses a custom report format that permits any number of
keys. If more than six keys are pressed simultaneously, the first six
are reported via interface 0 while subsequent keys are reported via
interface 2.

(Interface 1 uses a custom protocol for reprogramming the keyboard;
this can be controlled through userspace tools and is not of concern
for the present driver.)

The report descriptor for interface 2, however, is incorrect (for
report ID 0x04, the input field is marked as "array" rather than
"variable".) The descriptor appears to be correct in other respects,
so we simply replace the incorrect byte before parsing the descriptor.

HID: i2c-hid: Reorganize so ACPI and OF are separate modules

This patch rejiggers the i2c-hid code so that the OF (Open Firmware
aka Device Tree) and ACPI support is separated out a bit. The OF and
ACPI drivers are now separate modules that wrap the core module.

Essentially, what we're doing here:
* Make "power up" and "power down" a function that can be (optionally)
implemented by a given user of the i2c-hid core.
* The OF and ACPI modules are drivers on their own, so they implement
probe / remove / suspend / resume / shutdown. The core code
provides implementations that OF and ACPI can call into.

We'll organize this so that we now have 3 modules: the old i2c-hid
module becomes the "core" module and two new modules will depend on
it, handling probing the specific device.

As part of this work, we'll remove the i2c-hid "platform data"
concept since it's not needed.
