Mary Ruthven f82e8ab697 cbfs_spi: enable CBFS access in early romstage
Currently the CBFS mmap cannot be accessed at the beginning of romstage
because it waits until DRAM is initialized. This change first loads CBFS
into SRAM and then switches to using DRAM as the backing once it is
initialized.

BUG=chromium:210230
BRANCH=none
TEST=confirm that the cbfs can be access at the beginning and end of
romstage on different boards.
