ramips: dts: mt7621: add the missing XHCI power regulators
The USB power regulators are essential for the Mediatek XHCI
controller. If any of them is missing, the kernel will throw
a warning. Add fixed voltage io/vbus regulators to workaround
this issue. Fix the following warnings:
[ 7.514572] xhci-mtk 1e1c0000.xhci: supply vbus not found, using dummy regulator
[ 7.522375] xhci-mtk 1e1c0000.xhci: supply vusb33 not found, using dummy regulator
