platform/x86: amd-pmc: Fix compilation without CONFIG_SUSPEND

Since commit b1f66033cd ("platform/x86: amd-pmc: Move to later in the
suspend process") amd-pmc doesn't use traditional suspend resume
callback anymore but relies on functions only created declared when
CONFIG_SUSPEND is set.

Check for CONFIG_SUSPEND and only use those functions in those
circumstances.

Fixes: commit b1f66033cd ("platform/x86: amd-pmc: Move to later in the suspend process")
