[linux-sunxi] [PATCH 9/9] arm64: dts: allwinner: pinebook: Fix 5v0 boost regulator

[Samuel Holland]

Now that AXP803 GPIO support is available, we can properly model
the hardware. Replace the use of GPIO0-LDO with a fixed regulator
controlled by GPIO0. This boost regulator is used to power the
(internal and external) USB ports, as well as the speakers.
