[PATCH] ARM: dts: sun7i: olimex-lime2: Add regulators for GPIO banks

[Priit Laes <plaes@xxxxxxxxx>]

From: Priit Laes <priit.laes@xxxxxxx>

Make sure that A20 Olimex Lime2 pin bank regulators are
properly represented.

While pin banks A, B and F are connected to 3.3V static
regulator, pin banks E and G tied with LDO3 and LDO4 regulators
with 2.8V reference.
