xhci: Fix TRB prefetch issue of ZHAOXIN hosts
On some ZHAOXIN hosts, xHCI will prefetch TRB for performance
improvement. However this TRB prefetch mechanism may cross page boundary,
which may access memory not allocated by xHCI driver. In order to fix
this issue, two pages was allocated for a segment and only the first
page will be used. And add a quirk XHCI_ZHAOXIN_TRB_FETCH for this issue.
