Subject: 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.
