platform/x86/intel/pmc: Add suspend callback
Add a suspend callback to struct pmc for performing platform specific tasks
before device suspend. This is needed in order to perform GBE LTR ignore on
certain platforms at suspend-time instead of at probe-time and replace the
GBE LTR ignore removal that was done in order to fix a bug introduced by
commit 804951203aa5 ("platform/x86:intel/pmc: Combine core_init() and
core_configure()").
Fixes: 804951203aa5 ("platform/x86:intel/pmc: Combine core_init() and core_configure()")
