usb: xhci-mtk: fix broken streams issue on 0.96 xHCI

commit 6f978a30c9bb12dab1302d0f06951ee290f5e600 upstream.

The MediaTek 0.96 xHCI controller on some platforms does not
support bulk stream even HCCPARAMS says supporting, due to MaxPSASize
is set a default value 1 by mistake, here use XHCI_BROKEN_STREAMS
quirk to fix it.
