Subject: [PATCH v2] arm64: dts: allwinner: a64: Add gpio bank supply for A64-Olinuxino

Add the regulators for each bank on this boards.
For VCC-PL only add a comment on what regulator is used. We cannot add
the property without causing a circular dependency as the PL pins are
used to talk to the PMIC.

Signed-off-by: Emmanuel Vadot <manu@freebsd.org>

v2:
 - Remove vcc-pl-supply in r_pio as it cause a circular dependency.
