soc/intel/cmn/block/cpu: Perform PRMRR sync on all cores
This patch ensures to perform core PRMRR sync if SoC decides to
perform MP Init using coreboot native implementation.
Also, implement a function to allow calling `init_core_prmrr()`
for all CPUs from `before_post_cpus_init()`.
BUG=b:233199592
TEST=Build and boot google/kano to ChromeOS.
