soc/intel/common: Move update_mrc_cache after BS_DEV_ENUMERATE

This patch ensures that MRC cache data is already written
into SPI chip before SPI protected regions are getting locked
during BS_DEV_RESOURCES-BS_ON_EXIT.

This requirements are intended to support platform security
guideline where all required chipset registers are expected
to be in lock down stage before launching any 3rd party
code as in option rom etc.

coreboot has to change its execution order to meet those
requirements. Hence storing mrc cache data into SPI has
been moved right after pci enumeration is done, so that
SPI registers can be lock down before calling post pci
enumeration FSP NotifyPhase() API which is targeted to
be done in BS_DEV_ENABLE-BS_ON_ENTRY.

TEST=Ensure MRC training data is stored into SPI chip and power_
Resume autotest is passing.
