Missing compatibles and descriptions needed to implement R40 HDMI
pipeline are added.
For mixers only compatibles are added.
TCON description is expanded with R40 TV TCON compatibles. If the SoC
has TCON TOP unit, phandle to that unit has to be specified. Additional
clock has to be specified if SoC has TCON TOP and TCON is TV TCON.
New compatible is added for DWC HDMI PHY, which has additional clock
specified.
