baytrail: initialize chromeos EC if present in romstage
The EC needs to be initialized early in romstage. Therefore perform the call after console has been initialized in order to view any messages that the code may spit out.
BUG=chrome-os-partner:23387 BRANCH=None TEST=Built and booted with recovery mode and EC in RW. Noted that system reboots the EC.
