[PATCH] arm64: dts: rockchip: Fix vccio4-supply on rk3566-pinetab2

[Diederik de Haas]

Page 13 of the PineTab2 v2 schematic dd 20230417 shows VCCIO4's power
source is VCCIO_WL. Page 19 shows that VCCIO_WL is connected to
VCCA1V8_PMU, so fix the PineTab2 dtsi to reflect that.

Thanks for this patch.  As already discussed in private, this is
correct and safe to do, because both supplies are designated as
always-on, so please feel free to include:

Reviewed-by: Dragan Simic <dsimic@manjaro.org>

Though, I think this cleanup should also be propagated into the
stable kernels.  Right now this patch doesn't actually introduce
any functional changes, but maybe in the future there will be
some related driver or DT changes or improvements that may end up
relying on DT correction such as this one.

Fair point. Dunno if b4 picks this up automatically ...
