[PATCHv13 01/28] v4l2-device.h: always expose mdev

[Hans Verkuil <hverkuil@xs4all.nl>]

From: Hans Verkuil <hans.verkuil@cisco.com>

The mdev field is only present if CONFIG_MEDIA_CONTROLLER is set.
But since we will need to pass the media_device to vb2 and the
control framework it is very convenient to just make this field
available all the time. If CONFIG_MEDIA_CONTROLLER is not set,
then it will just be NULL.
