Subject: [PATCH v2 09/10] ARM: dts: sun9i: a80-optimus: Disable dummy regulators vcc3v0, vcc3v3, vcc5v0

These 3 regulators are provided in sunxi-common-regulators.dtsi.
3.0V/3.3V and 5.0V are commonly used voltages in Allwinner devices.
These dummy regulators provide a stand-in when bindings that require
one, but the real regulator is not supported yet.

Since these are no longer needed, we can disable them.
