arm64: dts: meson: odroid-c2: Add missing regulator linked to VDDIO_AO3V3 regulator

As per schematics TFLASH_VDD, TF_IO, VCC3V3 fixed regulator output which
is supplied by VDDIO_AO3V3.

While here, move the comment name with the signal name in the
schematics above the gpio property to make it consistent with other
regulators.
