[PATCH] arm64: dts: allwinner: h6: add PIO VCC bank supplies for Pine H64

[Icenowy Zheng]

The Allwinner H6 SoC features tweakable VCC for PC, PD, PG, PL and PM
banks.

This patch adds supplies for PC and PD banks on Pine H64 board. PG and
PM banks are used for Wi-Fi and should be added when Wi-Fi is added; PL
bank is where PMIC is attached, and currently if a PMIC regulator is
added for it a dependency loop will happen.

Not really. The regulator is still there, whether we use it or not. If
it's not used, then it will be left disabled so it doesn't really
change anything.

I guess we should fix that somehow

Okay, I will include them in the next revision.

But this patch is needed for eMMC to be functional again in HS200 mode, so I hope
it can get applied before this get fixed.
