This patch series is for enabling P0xx, Y2xx and Y4xx pixel formats for
intel's i915 driver.

In this patch series, Juha Pekka's patch series Gen10+ P0xx formats
https://patchwork.freedesktop.org/series/56053/ is combined with Swati's
https://patchwork.freedesktop.org/series/55035/ for Gen11+ pixel formats
(Y2xx and Y4xx).

P0xx pixel formats are enabled from GLK whereas Y2xx and Y4xx are enabled
from ICL platform.

These patches enable planar formats YUV420-P010, P012 and  P016
(Intial 3 patches of Juha) for GLK+ platform and packed format YUV422-Y210,
Y212 and Y216 and YUV444-Y410, Y412, Y416 for 10, 12 and 16 bits for ICL+
platforms.

IGT validating all these pixel formats is written by Maarten Lankhorst 
https://patchwork.freedesktop.org/patch/284508/

IGT needs libraries for pixman and cairo to support more than 8bpc. Need 
cairo >= 1.17.2 and pixman-1 >= 0.36.0.

Tested with custom cairo and pixman. P0xx and Y2xx successfully validated for
HDR planes, SDR planes having CRC mismatch (known bug for all YUV formats).

v3: fixed missing tab for XYUV8888 (JP)
