A number of Cezanne systems report IRQ1 as a wakeup source when it's not
actually a wakeup. This can cause problems for certain ACPI events. The
following fix went upstream that fixed it:
commit 8e60615e8932 ("platform/x86/amd: pmc: Disable IRQ1 wakeup for
RN/CZN")
It was reported that this fix actually helped here with older kernels too:

So backport this fix to 5.15.y as well. The backport is done by hand
because the driver has changed significantly. To backport this also
requires the SMU version reading function which was introduced from:
commit f6045de1f532 ("platform/x86: amd-pmc: Export Idlemask values based
on the APU")
So backport that part of that commit as well.
