platform/x86: amd-pmc: Fix compilation without CONFIG_SUSPEND
Since commit b1f66033cd4e ("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 b1f66033cd4e ("platform/x86: amd-pmc: Move to later in the suspend process")
