baytrail: Fix XHCI problems and re-enable
- a few clock gating bits were set improperly and were preventing the system from transitioning out of S0 state. - the XHCC registers were not getting the top byte set properly which includes things like DMA write request size and request boundary crossing control. This was causing memory corruption.
BUG=chrome-os-partner:23635 BRANCH=rambi TEST=build and boot kernel from USB on rambi with XHCI driver
