soc/intel/skylake: Move update microcode from cbfs to mp_ops callbacks

FIT is already loading microcode before CPU Reset. So, we need
not update the microcode again in RO FW in bootblock.

But we need to update in RW FW if there is any new ucode version.
So, added the update microcode function in get_microcode_info callback
before MP Init to make sure BSP is using the microcode from cbfs.

BUG=none
BRANCH=none
TEST=Build and Boot poppy
