soc/amd/mendocino/acpi: remove RTC wake workaround
Commit 78ee4889dc32 ("soc/amd/cezanne/acpi: Add support for RTC
workaround") added a workaround for the Cezanne silicon. This was copied
to the Mendocino code, but from both the discussion in b:209705576 and
the referenced amd_pmc_verify_czn_rtc function in drivers/platform/x86/
amd/pmc.c that is only called if pdev->cpu_id == AMD_CPU_ID_CZN is true
Mendocino doesn't need that workaround, so remove it.
TEST=Running suspend_stress_test -c 5 on Chausie shows no errors
