platform/x86/amd: pmc: Remove more CONFIG_DEBUG_FS checks

commit 82b103d6c046 ("platform/x86/amd: pmc: remove CONFIG_DEBUG_FS
checks") removed most CONFIG_DEBUG_FS checks, but there were some
left that were reported to cause compile test failures.

Remove the remaining checks, and also the unnecessary CONFIG_SUSPEND
used in the same place.
