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
