First usb and third pcie controller on mt7988 need a xs-phy to work
properly.

Signed-off-by: Frank Wunderlich <frank-w@public-files.de>

v3:
- drop unneeded properties and compatibles from topmisc
- xsphy unit name not changed because binding requires this name (not only phy)
- also not changed port names to be clear abour which phy is used (mt7988 also have tphy)
- change offset to have clean syscon (without power controller)
