There are three USB controllers on mt8196, each controller's wakeup
control is different, add some specific versions for them.

Since all of the USB controllers of the MT8196 SoC are behind MTU3, and
since the wakeup control for all of them will be handled by the MTU3 driver
and *not* by the xhci-mtk driver....

NACK!

Please drop this commit.

Cheers,
Angelo
