sna: Added AYUV format support for textured and sprite video adapters.

v2: Renamed DRM_FORMAT_XYUV to DRM_FORMAT_XYUV8888.
    Added comment about AYUV byte ordering in Gstreamer.

v3: Removed sna_composite_op flags related change to the separate patch.

v4: Fixed review comments, done code refactoring

v5: Fixed following review comments:
    - Fixed comment in shader code for ayuv kernel.
    - Fixed naming to VIDEO_AYUV_BT601/BT709 for ayuv kernels.
    - Removed duplicate gen9_kernel parameter, left from previous patches
    - Added colorspace handling for new AYUV kernel
    - Fixed naming of sna_copy_packed_data_ayuv to sna_copy_ayuv_data
    - Started using standard bswap_32 function for byte swapping in sna_copy_ayuv_data
    - Removed redundant code in sna_copy_ayuv_data so that it looks more neat
    - Fixed XVIMAGE_AYUV structure initialization to contain proper byte sequence for GST
    - Fixed bogus comment about subsampling for DRM_FORMAT_XYUV8888
    - Fixed AYUV advertisement for all platforms
    - Removed unnecessary RGB888 declaration.

v6:
    - Fixed surface format not to use alpha as supposed
    - Now doing byte swapping always during copy
    - Changed hack, required for GST to work to be at one place
    - Fixed invalid sampling values for XVIMAGE_AYUV
    - Fixed sprite format checking order and images_ayuv definition.

v7:
    - Removed reverse_bytes bool parameter, now swapping bytes
      for XYUV unconditionally both for textured and sprite modes.

v8:
    - Added gen9_images structure, in order to expose AYUV format to
      proper platforms.
