baytrail: clear the pmc wake status registers
The PMC in baytrail maintains an additional set wake status in memory-mapped registers. If these bits aren't cleared the device won't be able to go to S5 or S3 without being immediately woken up. Therefore clear these registers. BUG=chrome-os-partner:24913 BRANCH=rambi,squawks TEST=Ensured PRSTS bit 4 is cleared after a reboot and S3 and S5 work correctly.
