Subject: [PATCH V6 14/20] platform/x86/intel/pmc/mtl: Use return value from pmc_core_ssram_init()
Instead of checking for a NULL regbase, use the return value from
pmc_core_ssram_init() to check if PMC discovery was successful. If not, use
the legacy enumeration method (which only works for the primary PMC).
