Verified with "-pix_fmt yuv420p16le", the output image is good as expected.

Verified with HEVC QSV decode + software CSC:
ffmpeg -hwaccel qsv -hwaccel_device /dev/dri/renderD128 -v verbose -c:v hevc_qsv -load_plugin hevc_hw -i ./Main_422_10_A_RExt_Sony_2.bin -vf hwdownload,format=y210le -pix_fmt yuv420p16le out.yuv

This v2 version  is for the missing chrToYV12/ lumToYV12 entry for y210.
