Allwiner SoCs with DesignWare HDMI controller all come with a "HVCC"
pin, which is the VCC of HDMI part.

Add a supply property to specify HVCC's regulator in the device tree.

"hdmi" doesn't sound like the name of the supply. "hvcc" or just "vcc" 
would be more appropriate.

Okay. In original versions it used to be "hvcc-supply", and
I will pick the name again.
