Add device tree bindings for the TH1520 Video Output (VO) subsystem
clock controller. The VO sub-system manages clock gates for multimedia
components including HDMI, MIPI, and GPU.
Document the VIDEO_PLL requirements for the VO clock controller, which
receives its input from the AP clock controller. The VIDEO_PLL is a
Silicon Creations Sigma-Delta (integer) PLL typically running at 792 MHz
with maximum FOUTVCO of 2376 MHz.
This binding complements the existing AP sub-system clock controller
which manages CPU, DPU, GMAC and TEE PLLs.
