drm/bridge: dw-hdmi: Add SCDC and TMDS Scrambling support
Add support for SCDC Setup for TMDS Clock > 3.4GHz and enable TMDS
Scrambling when supported or mandatory.
This patch also adds an helper to setup the control bit to support
the high TMDS Bit Period/TMDS Clock-Period Ratio as required with
TMDS Clock > 3.4GHz for HDMI2.0 3840x2160@60/50 modes.
These changes were based on work done by Huicong Xu <[email protected]>
and Nickey Yang <[email protected]> to support HDMI2.0 modes
on the Rockchip 4.4 BSP kernel at [1]
