EC-100 and Odroid-C1 use a "copy" of the VCCK regulator as "VDDEE"
regulator. VDDEE supplies the Mali GPU and various other bits within
the SoC.

The VDDEE regulator is not exclusive to the Mali GPU so it must not
change it's voltage. The GPU OPP table has a fixed voltage for all
frequencies of 1.10V. This matches with what u-boot sets on my EC-100
and Odroid-C1.

Changes since v1 at [0]:
- fixed node name for Odroid-C1 (which was vcck instead of vddee in v1)
- updated cover-letter since all dependencies made it into v5.3-rc1
- rebased onto v5.3-rc1
