platform/x86/amd: pmc: Disable IRQ1 wakeup for RN/CZN

By default when the system is configured for low power idle in the FADT
the keyboard is set up as a wake source.  This matches the behavior that
Windows uses for Modern Standby as well.

It has been reported that a variety of AMD based designs there are
spurious wakeups are happening where two IRQ sources are active.

For example:
```
PM: Triggering wakeup from IRQ 9
PM: Triggering wakeup from IRQ 1
```

In these designs IRQ 9 is the ACPI SCI and IRQ 1 is the keyboard.
One way to trigger this problem is to suspend the laptop and then unplug
the AC adapter.  The SOC will be in a hardware sleep state and plugging
in the AC adapter returns control to the kernel's s2idle loop.

Normally if just IRQ 9 was active the s2idle loop would advance any EC
transactions and no other IRQ being active would cause the s2idle loop
to put the SOC back into hardware sleep state.

When this bug occurred IRQ 1 is also active even if no keyboard activity
occurred. This causes the s2idle loop to break and the system to wake.

This is a platform firmware bug triggering IRQ1 without keyboard activity.
This occurs in Windows as well, but Windows will enter "SW DRIPS" and
then with no activity enters back into "HW DRIPS" (hardware sleep state).

This issue affects Renoir, Lucienne, Cezanne, and Barcelo platforms. It
does not happen on newer systems such as Mendocino or Rembrandt.

It's been fixed in newer platform firmware.  To avoid triggering the bug
on older systems check the SMU F/W version and adjust the policy at suspend
time for s2idle wakeup from keyboard on these systems. A lot of thought
and experimentation has been given around the timing of disabling IRQ1,
and to make it work the "suspend" PM callback is restored.
