Makes selection of d3d11va device type by default and over DirectX 9,
which might break users with older drivers/systems.
DCH driver with Gen6th support should be still fine.
Decode, encode, transcode have been validated.
child_device_type option is responsible for d3d11va/dxva2 device selection
Usage examples:
DirectX 11
-init_hw_device qsv:hw,child_device_type=d3d11va
DirectX 9 is still supported but requires explicit selection
-init_hw_device qsv:hw,child_device_type=dxva2
