platform/x86/amd: pmc: Add Lenovo Legion Go 2 to pmc quirk list
The Lenovo Legion Go 2 takes a long time to resume from suspend.
This is due to it having an nvme resume handler that interferes
with IOMMU mappings. It is a common issue with older Lenovo
laptops. Adding it to that quirk list fixes this issue.

platform/x86/amd/pmc: Add spurious_8042 to Xbox Ally
The Xbox Ally features a Van Gogh SoC that has spurious interrupts
during resume. We get the following logs:
atkbd_receive_byte: 20 callbacks suppressed
atkbd serio0: Spurious ACK on isa0060/serio0. Some program might be trying to access hardware directly.
So, add the spurious_8042 quirk for it. It does not have a keyboard, so
this does not result in any functional loss.

platform/x86/amd/pmc: Add PCSpecialist Lafite Pro V 14M to 8042 quirks list
Every other s2idle cycle fails to reach hardware sleep when keyboard
wakeup is enabled. This appears to be an EC bug, but the vendor
refuses to fix it.
It was confirmed that turning off i8042 wakeup avoids ths issue
(albeit keyboard wakeup is disabled). Take the lesser of two evils
and add it to the i8042 quirk list.

platform/x86/amd/pmc: Declare quirk_spurious_8042 for MECHREVO Wujie 14XA (GX4HRXL)
MECHREVO Wujie 14XA (GX4HRXL) wakes up immediately after s2idle entry.
This happens regardless of whether the laptop is plugged into AC power,
or whether any peripheral is plugged into the laptop.
Similar to commit a55bdad5dfd1 ("platform/x86/amd/pmc: Disable keyboard
wakeup on AMD Framework 13"), the MECHREVO Wujie 14XA wakes up almost
instantly after s2idle suspend entry (IRQ1 is the keyboard):
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 9
2025-04-18 17:23:57,588 DEBUG: PM: Triggering wakeup from IRQ 1
Add this model to the spurious_8042 quirk to workaround this.
This patch does not affect the wake-up function of the built-in keyboard.
Because the firmware of this machine adds an insurance for keyboard
wake-up events, as it always triggers an additional IRQ 9 to wake up the
system.
