soc/intel/apollolake: Add save/restore variable MRC cache

Apollolake MRC cache is divided into two regions: constant and variable.
    Currently they are clubbed together. Since variable data changes across
    cold reboot it triggers invalidation of the whole cache region. This
    change declubs the data, adds routines to load/store variable data on
    flash.

BUG=chrome-os-partner:57515
    TEST=with patch series applied: cold reboot, make sure MRC is not
    updated. Do S3 suspend/resume cycle.
