MFC r352556:
Add quirk for XHCI(4) controllers to support USB control transfers
above 1Kbyte. It might look like some XHCI(4) controllers do not
support when the USB control transfer is split using a link TRB. The
next NORMAL TRB after the link TRB is simply failing with XHCI error
code 4. The quirk ensures we allocate a 64Kbyte buffer so that the
data stage TRB is not broken with a link TRB.
