soc/intel/cmn/block/cpu: Set BIOS_DONE on all CPUs
As per Intel Processor EDS, BIOS_DONE bit needs to be set on
all CPUs via MSR.
Also, implement a function to perform any SoC recommended CPU
programming prior to post CPUs init. At present calling
`cpu_soc_bios_done()` for all CPUs from `before_post_cpus_init()`.
Note: It is expected that `before_post_cpus_init()` will be
extended with other CPU programming recommendations in follow up
patches, for example: reload microcode patch etc.
BUG=b:233199592
