Subject: [PATCH v2] ARM: dts: sun8i-r40: remove unused GPIO regulator

Banana Pi M2 Ultra V1.1 board resets immediately when the usb core tries
to setup PH23 GPIO. It turned out that the V1.0 board USB-A ports are
always power supplied and according to the board scheme PH23 is simply
not connected.

So remove the PH23 setup: Doesn't harm V1.0 (with R40) and let V1.1
(with A40i) start.
