media: subdev: Add checks for subdev features
Add some checks to verify that the subdev driver implements required
features.
A subdevice that supports streams (V4L2_SUBDEV_FL_STREAMS) must do one
of the following:
- Implement neither .enable/disable_streams() nor .s_stream(), if the
subdev is part of a video driver that uses an internal method to
enable the subdev.
- Implement only .enable/disable_streams(), if support for legacy
sink-side subdevices is not needed.
- Implement .enable/disable_streams() and .s_stream(), if support for
legacy sink-side subdevices is needed.
At the moment the framework doesn't check this requirement. Add the
check.
