Previously, we were writing to cbmem after memory training and then
writing the training data from cbmem to mrc_cache in ramstage. We
were doing this because we were unable to read/write to SPI
simultaneously on older x86 chips. Now that newer chips allow for
simultaneously reads and writes, we can move the mrc_cache update into
romstage. This is beneficial if there is a reboot for some reason
after memory training but before the previous mrc_cache_stash_data
call originally in ramstage. If this happens, we would lose all the
mrc_cache training data in the next boot even though we've already
performed the memory training.
Added new config BOOT_DEVICE_SPI_FLASH_NO_EARLY_WRITES to accomodate
older x86 platforms that don't do mmapping but still want to use the
cbmem to store the mrc_cache data in order to write the mrc_cache data
back at a later time. We are maintaining the use of cbmem for these
older platforms because we have no way of validating the earlier write
back to mrc_cache at this time.

TEST=reboot from ec console. Make sure memory training happens.
