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.
