The SDK doesn't support VC1 encoding. In addition, both
MFX_PROFILE_VC1_SIMPLE and MFX_PROFILE_HEVC_MAIN are 1 in the SDK, HEVC
main profile is recognized as simple profile in the verbose output if
don't remove VC1 profiles.

$ ffmpeg -v verbose -qsv_device /dev/dri/renderD129 -f lavfi -i
yuvtestsrc -c:v hevc_qsv -f null -

[hevc_qsv @ 0x55bdf7eb4eb0] profile: simple; level: 21
