[Libva] [PATCH v3 intel-driver 6/8] config: fix supported set of chroma formats for JPEG decode.

[Gwenole Beauchesne]

If the hardware supports JPEG decoding, then we have to expose the
right set of chroma formats for the output (decoded) VA surface. In
particular, we could support YUV 4:0:0, 4:1:0, 4:2:2 and 4:4:4.

v2: export support for YUV 4:0:0 (grayscale) too [Haihao]
