Input: remove evbug driver

I've never heard of anyone having used this driver for debugging at least
in over past decade or so. Since we have tools like evtest, this driver
seems to be rather superficial.

Also, it apparently causes confusion among people who accidentaly enable
CONFIG_INPUT_EVBUG and are annoyed/confused by their kernel log being
spammed by a lot of useless data.

Let's just remove it.

Input: tests - modular KUnit tests should not depend on KUNIT=y

While KUnit tests that cannot be built as a loadable module must depend
on "KUNIT=y", this is not true for modular tests, where it adds an
unnecessary limitation.

Fix this by relaxing the dependency to "KUNIT".

Input: Add KUnit tests for some of the input core helper functions

The input subsystem doesn't currently have any unit tests, let's add a
CONFIG_INPUT_KUNIT_TEST option that builds a test suite to be executed
with the KUnit test infrastructure.

For now, only three tests were added for some of the input core helper
functions that are trivial to test:

* input_test_polling: set/get poll interval and set-up a poll handler.

* input_test_timestamp: set/get input event timestamps.

* input_test_match_device_id: match a device by bus, vendor, product,
version and events capable of handling.

But having the minimal KUnit support allows to add more tests and suites
as follow-up changes. The tests can be run with the following command:

$ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/input/tests/

Synaptics uses the Register Mapped Interface (RMI) protocol as a
communications interface for their devices. This driver adds the core
functionality needed to interface with RMI4 devices.

RMI devices can be connected to the host via several transport protocols
and can supports a wide variety of functionality defined by RMI functions.
Support for transport protocols and RMI functions are implemented in
individual drivers. The RMI4 core driver uses a bus architecture to
facilitate the various combinations of transport and function drivers
needed by a particular device.

Input: export LEDs as class devices in sysfs

This change creates a new input handler called "leds" that exports LEDs on input
devices as standard LED class devices in sysfs and allows controlling their
state via sysfs or via any of the standard LED triggers. This allows to
re-purpose and reassign LDEs on the keyboards to represent states other
than the standard keyboard states (CapsLock, NumLock, etc).

The old API of controlling input LEDs by writing into /dev/input/eventX
devices is still present and will take precedence over accessing via LEDs
subsystem (i.e. it may override state set by a trigger). If input device is
"grabbed" then requests coming through LED subsystem will be ignored.

kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERT

The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option
is used to configure any non-standard kernel with a much larger scope than
only small devices.

This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes
references to the option throughout the kernel. A new CONFIG_EMBEDDED
option is added that automatically selects CONFIG_EXPERT when enabled and
can be used in the future to isolate options that should only be
considered for embedded systems (RISC architectures, SLOB, etc).

Calling the option "EXPERT" more accurately represents its intention: only
expert users who understand the impact of the configuration changes they
are making should enable it.

the backend in dom0 needs both drivers, and will refuse to complete

Input: add input event to APM event bridge

This patch adds a very simple input power event to APM user suspend
event bridge. Its currently only works for the systems using the
emulated APM driver but could easily be extended to work with anything
with a true APM BIOS too.

This covers a standard embedded system need which is to suspend when the
user presses a suspend button. It leaves options open to system
integrators to ignore (or unload) this code and implement their own more
complex event handling system.

Its hidden behind the EMBEDDED Kconfig option since its only likely to
be of use to embedded style systems. It can be built as a module so the
"hardcoded" policy can easily be removed from the kernel at runtime if
desired too.
