The Surface Laptop 4 AMD has used the AMD0005 to identify this
controller instead of using the appropriate ACPI ID AMDI0005. The
AMD0005 needs the same special casing as AMDI0005.

It was reported that on "HP ENVY x360" that power LED does not come
back, certain keys like brightness controls do not work, and the fan
never spins up, even under load on 5.14 final.
In analysis of the SSDT it's clear that the Microsoft UUID doesn't
provide functional support, but rather the AMD UUID should be
supporting this system.
Because this is a gap in the expected logic, we checked back with
internal team. The conclusion was that on Windows AMD uPEP *does*
run even when Microsoft UUID present, but most OEM systems have
adopted value of "0x3" for supported functions and hence nothing
runs.
Henceforth add support for running both Microsoft and AMD methods.
This approach will also allow the same logic on Intel systems if
desired at a future time as well by pulling the evaluation of
`lps0_dsm_func_mask_microsoft` out of the `if` block for
`acpi_s2idle_vendor_amd`.

It was reported by a user with a Dell m15 R5 (5800H) that
the keyboard backlight was turning on when entering suspend
and turning off when exiting (the opposite of how it should be).
The user bisected it back to commit 5dbf50997578 ("ACPI: PM:
s2idle: Add support for new Microsoft UUID"). Previous to that
commit the LEDs didn't turn off at all. Confirming in the spec,
these were reversed when introduced.
Fix them to match the spec.

AMD systems with uPEP HID AMDI007 should be using revision 2 and

When using s2idle on a variety of AMD notebook systems, they are
experiencing spurious events that the EC or SMU are in the wrong
state leading to a hard time waking up or higher than expected
power consumption.
These events only occur when the EC GPE is inadvertently set as a wakeup
source. Originally the EC GPE was only set as a wakeup source when using
the intel-vbtn or intel-hid drivers in commit 10a08fd65ec1 ("ACPI: PM:
Set up EC GPE for system wakeup from drivers that need it") but during
testing a reporter discovered that this was not enough for their ASUS
Zenbook UX430UNR/i7-8550U to wakeup by lid event or keypress.
Marking the EC GPE for wakeup universally resolved this for that
reporter in commit b90ff3554aa3 ("ACPI: PM: s2idle: Always set up EC GPE
for system wakeup").
However this behavior has lead to a number of problems:
* On both Lenovo T14 and P14s the keyboard wakeup doesn't work, and
sometimes the power button event doesn't work.
* On HP 635 G7 detaching or attaching AC during suspend will cause
the system not to wakeup
* On Asus vivobook to prevent detaching AC causing resume problems
* On Lenovo 14ARE05 to prevent detaching AC causing resume problems
* On HP ENVY x360 to prevent detaching AC causing resume problems
As there may be other Intel systems besides ASUS Zenbook UX430UNR/i7-8550U
that don't use intel-vbtn or intel-hid, avoid these problems by only
universally marking the EC GPE wakesource on non-AMD systems.

Some AMD Systems with uPEP _HID AMD004/AMDI005 have an off by one bug
in their function mask return. This means that they will call entrance
but not exit for matching functions.
Other AMD systems with this HID should use the Microsoft generic UUID.
AMD systems with uPEP HID AMDI006 should be using the Microsoft method.

Refactor common code to prepare for upcoming changes.
* Remove unused struct.
* Print error before returning.
* Frees ACPI obj if _DSM type is not as expected.
* Treat lps0_dsm_func_mask as an integer rather than character
* Remove extra out_obj
* Move rev_id

These are supposedly not required for AMD platforms,
but at least some HP laptops seem to require it to
properly turn off the keyboard backlight.

Two local variables in drivers/acpi/x86/s2idle.c are never read, so
drop them along with the code updating their values (in vain).

Some code in drivers/acpi/sleep.c (which is regarded as a generic
file) related to suspend-to-idle support has grown direct dependencies
on x86, but in fact it has been specific to x86 (which is the only
user of it) anyway for a long time.
For this reason, move that code to a separate file under acpi/x86/
and make it build and run as before under the right conditions.
While at it, rename a vendor checking function in that code and
consistently use acpi_handle_debug() for printing debug-related
information in it.
No expected functional impact.
