intel/fsp2_0: Issue hard reset in S3 resume for invalid mrc cache data

In S3 resume, for cases if valid mrc cache data is not found or
RECOVERY_MRC_CACHE hash verification fails, the S3 data pointer
would be null and bootmode is set to BOOT_WITH_FULL_CONFIGURATION.
This gets memory to be retrained in S3 flow. Data context including
that of imdr root pointer would be lost, invoking a hard reset in
romstage post memory init. Issuing hard reset before memory init,
saves fsp memory initialization and training overhead.

BUG=b:70973961
BRANCH=None
TEST=Verify S3 resume flows on soraka.
