The PWM_D output is used for the VDDEE PWM regulator which supplies for
example the Mali GPU on the EC-100 and Odroid-C1 boards. Add the output
pin the VDDEE regulators can be added.

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.
