USB: xhci: Scratchpad buffer allocation

Allocates and initializes the scratchpad buffer array (XHCI 4.20).  This is an
array of 64-bit DMA addresses to scratch pages that the controller may use
during operation.  The number of pages is specified in the "Max Scratchpad
Buffers" field of HCSPARAMS2.  The DMA address of this array is written into
slot 0 of the DCBAA.
