Static CBMEM / CAR: Flag boards with BROKEN_CAR_MIGRATE
Use of CAR_GLOBAL is not safe after CAR is torn down, unless the
board properly implements EARLY_CBMEM_INIT.
Flag vulnerable boards that only do cbmem_recovery() in romstage on S3
resume and implementation with Intel FSP that invalidates cache before
we have a chance to copy the contents.
