[PATCH 2/4] ARM: dts: meson8b: ec100: add the VDDEE regulator

[Martin Blumenstingl]

The VDDEE regulator is basically a copy of the VCCK regulator. VDDEE
supplies for example the Mali GPU and is controlled by PWM_D instead of
PWM_C.

Add the VDDEE PWM regulator and make it the supply of the Mali GPU.
