Internally Mali DP uses an RGB pipeline so video layers that support
YUV input buffers need to convert the input data to RGB. The YUV
buffers can have various encodings and this patch introduces support
for BT.601, BT.709 and BT.2020 encodings, both limited and full ranges.
This patch adds support for specifying the color encoding of the
input buffers for the planes that are backed by the video layers
and programs the YUV2RGB coefficients into hardware based on the
selected encoding.

Enable the scaling engine for upscaling a single plane using the polyphase
scaler. No image enhancement support or downscaling yet*, and composition
result scaling is not implemented.
* Downscaling a plane requires mclk > pxlclk.

All DPs have a COLORADJ matrix which is applied prior to output gamma.
Attach that to the CTM property. Also, ensure the input CTM's coefficients
can fit in the DP registers' Q3.12 format.

Add gamma via the DRM GAMMA_LUT/GAMMA_LUT_SIZE CRTC
properties. The expected LUT size is 4096 in order
to produce as accurate a set of segments as possible.
This version uses only the green channel's gamma curve
to set the hardware curve on DP550/650. For the sake of
simplicity, it uses the same table of coefficients for
all 3 curves on DP500.

Use rectangle 1 as a generic plane. Existing code already sets the smart
layer bounding box size + offset. The rectangles' offsets are relative
to the bounding box, so there is no need to set R1's offset (reset value
is 0), just its size which is the same as the bounding box.

Hardware has multiple (2 or 3, depending on model) stride
registers per layer; add a function that correctly takes that
into account. On hardware that only has 2 stride registers,
ensure that 3-plane (YUV) content has identical strides
for both chroma planes.
