Subject: [PATCH 5/5] ARM: sun7i: cubieboard2: Enable the AXP209

Add the AXP209 PMIC with the regulators in use on the cubie2.

The RTC regulator can be disabled, but since the RTC driver doesn't grab the
regulator for now, the driver wouldn't work anymore.

Signed-off-by: Maxime Ripard <maxime.ripard@...e-electrons.com>
