Changes since v7:
- Describe HDMI PHY PLL output in the device tree. The hdmitx_dig_cts
clock is not a child of tvdpll_445p5m, but is an output of the
HDMI PHY module, which is routed back into the TOP clock module
for further divison and muxing.
- The hdmi_sel mux defaults to its 26 MHz input - switch it to the
HDMI PHY PLL output.
