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.

platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles

platform/x86/amd: pmc: Require at least 2.5 seconds between HW sleep cycles

When an APU exits HW sleep with no active wake sources the Linux kernel will
rapidly assert that the APU can enter back into HW sleep. This happens in a
few ms. Contrasting this to Windows, Windows can take 10s of seconds to
enter back into the resiliency phase for Modern Standby.

For some situations this can be problematic because it can cause leakage
from VDDCR_SOC to VDD_MISC and force VDD_MISC outside of the electrical
design guide specifications. On some designs this will trip the over
voltage protection feature (OVP) of the voltage regulator module, but it
could cause APU damage as well.

To prevent this risk, add an explicit sleep call so that future attempts
to enter into HW sleep will have enough time to settle. This will occur
while the screen is dark and only on cases that the APU should enter HW
sleep again, so it shouldn't be noticeable to any user.
