soc/intel/common: Add save/restore for variable MRC data

Piggy-back on existing MRC cache infrastructure to store variable MRC data.

Only one set of data can be valid at given point of time. Currently this
    magically happens because region alignment is forced to 0x1000 and region
    itself is of the same size. This needs to be somehow programmatically
    enforced.
