baytrail: ensure init_chromeos() is called in romstage
The TPM needs to have the TPM_Startup command sent to it
on all boot paths. The call init_chromeos() in romstage_common()
fulfills this requirement.
BUG=chrome-os-partner:24057
BRANCH=None
TEST=Built and booted. Was able to suspend to ram multiple times
in a row.
