arm64: dts: mediatek: mt8195: Add power domain to U3PHY1 T-PHY

[ Upstream commit a9f6721a3c92764582ed12296292fda4a7f2dd25 ]

Assign power domain to the U3PHY1 T-PHY in otder to keep this PHY
alive after unused PD shutdown and to be able to completely cut
and restore power to it, for example, to save some power during
system suspend/sleep.
