platform/x86/intel/pmc: Add ssram_init flag in PMC discovery in Meteor Lake

Browse source

If PMC discovery using pmc_core_ssram_init() was unsuccessful for the
Meteor Lake platform, the legacy enumeration method is used. In this
case pci device struct for the PMC SSRAM is not available
and pmc_core_ssram_get_lpm_reqs() will not work. Add ssram_init flag to
indicate if the PMC SSRAM initialization was successful or not. Call
pmc_core_ssram_get_lpm_reqs() only if the ssram_init flag is set to true.
