For devices that don't have non-V4L2 media controller nodes, this would
work, but if we ever add ALSA, DVB, IIO, etc to the media controller,
then we may have troubles.
That's why I opted to add a macro for checking for the V4L2 subdev.
This is more future-proof, as other patches may be adding other
non-V4L2 types of MC entities have the potential of breaking codes like
the above.
