From: Haihao Xiang <haihao.xiang@intel.com>

XV30 is used for 10bit 4:4:4 content in FFmpeg VAAPI, so XV30 should be
used for 10bit 4:4:4 content in FFmpeg QSV too because QSV is based on
VAAPI on Linux. However the SDK only declares support for Y410 but does
nothing with the alpha in Y410, so this commit fudged a mapping between
AV_PIX_FMT_XV30 and MFX_FOURCC_Y410.
