baytrail: set max frequency early in romstage

Set the BSP to operate at max frequency early in romstage.
The call to punit_init() is when the frequency actually ramps as
that makes the punit actually start working.

BUG=chrome-os-partner:22857
BRANCH=None
TEST=Built and booted. Noted operating frequency status is max.
