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:
Link: https://gitlab.freedesktop.org/drm/amd/-/issues/1921#note_1770257
So backport this fix to 5.15.y as well.
This backport is dependent upon being able to read the SMU version which
happened in a different commit. So backport that commit and follow up fixes
as well.
v1->v2:
* Split into multiple commits
* Catch some fixes for reading SMU version too
