These two things were in one function. Split into two. This looks

The MIPI DSI controller in Allwinner A64 is similar to A33.
But unlike A33, A64 doesn't have DSI_SCLK gating so it is valid
to have separate compatible for A64 on the same driver.
DSI_SCLK uses mod clock-names on dt-bindings, so the same
is not required for A64.

This patch adds clocking support for the YUV420 output from the
Amlogic Meson SoCs Video Processing Unit to the HDMI Controller.
The YUV420 is obtained by generating a YUV444 pixel stream like
the classic HDMI display modes, but then the Video Encoder output
can be configured to down-sample the YU
Now the DW-HDMI Controller supports the HDMI2.0 modes, enable support
for these modes in the connector if the platform supports them.
We limit these modes to DW-HDMI IP version >= 0x200a which
are designed to support HDMI2.0 display modes.

This patchset is based on Boris's v4 "drm: Add support for bus-format
negotiation" at [1]
patchset to implement full bus-format negotiation for DW-HDMI, including YUV420
support and
10/12/16bit YUV444, YUV422 and RGB. The Color Space Converter support is
already implemented.

During phy compliance auto test mode source need to read
requested test pattern from sink through DPCD. After processing
the request source need to set the pattern. So set/get method
added in drm layer as it is DP protocol.
v2: As per review feedback from Manasi on RFC version,
- added dp revision
Driver changes mainly to process the request coming from Test equipment
as short pulse hpd interrupt to change link-pattern/v-swing/pre-emphasis
Complete auto test suite takes much lesser time than manual run.
