[Intel-gfx] [PATCH 0/4] Enable P010, P012 and P016 formats for GLK/CNL

[Juha-Pekka Heikkila]

These patches enable P010, P012 and P016 formats for GLK and CNL.
These formats are similar to NV12 extending from 8 bits per channel
to 10, 12 and 16 bits per channel.

For user space components there is in IGT kms_available_modes_crc test
which can test these new modes, test need to be recompiled with 
DRM_FORMAT_Pxxx definitions in place. For VLC media player I've made
KMS video out plugin which will be able to show these new modes. This vout
plugin is still work in progress, first version of my plugin can be seen
here: https://mailman.videolan.org/pipermail/vlc-devel/2018-May/119013.html

Vidya and Maarten here as CC as you guys were doing lot of NV12 stuff
earlier and my patches extend NV12.
