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.

as working on Juno.

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.

We're going to use the same format list for output formats, so rename
everything related to input formats to avoid confusion.

Different hardware versions have different requirements when it comes to
pitch alignment. Add a function which can be used to check pitch
alignment for a device.

Add support for the new family of Display Processors from ARM Ltd.
This commit adds basic support for Mali DP500, DP550 and DP650
parts, with only the display engine being supported at the moment.
