region_file_update_data_arr: Modify region_file with array of buffers
Add region_file_update_data_arr, which has the same functionality as
region_file_update_data, but accepts mutliple data buffers. This is
useful for when we have the mrc_metadata and data in non-contiguous
addresses, which is the case when we bypass the storing of mrc_cache
data into the cbmem.
BUG=b:150502246
BRANCH=None
TEST=reboot from ec console. Make sure memory training happens.
reboot from ec console. Make sure that we don't do training again.
