nb/intel/x4x: Issue a hard reset with empty MRC cache on warm reset

The dram controller cannot fully initialize the dram on warm
reset (receive enable calibration consistently fails) therefore
requiring cached timings.

This option is mostly useful when rebooting after having flashed a new
rom which overwrites the mrc cache region.
