dt-bindings: display: meson-dw-hdmi: add missing power-domain

All Amlogic instances of the Synopsys HDMI controller need a power domain
enabled. This is currently missing because the Amlogic HDMI driver directly
pokes the power domain controller registers, which it should not do.

Instead The HDMI controller should use the power controller.
Fix the bindings accordingly.
