Allwinner fixes - round 2
One additional fix regarding HDMI on the R40 SoC.
Based on preliminary tests and code dumps for the R40, it was thought
that the whole HDMI block was the same on the R40 and A64.
Recent tests regarding the A64 showed that this was not the case. The
HDMI PHY on the A64 only has one clock parent. How this occurs at the
hardware level is unclear, as Allwinner has not given any feedback on
this matter. Nevertheless it is clear that the hardware acts differently
between the A64 and R40 in such a way that the R40's HDMI PHY is not
backward compatible with the A64's. As such we need to drop the fallback
compatible string in the R40's device tree. This was added in v4.19-rc1.
