Embed video_device structs vdev and vbi_dev in au0828_dev.
With this change, dynamic allocation and error path logic
in au0828_analog_register() is removed as it doesn't need
to allocate and handle allocation errors. Unregister path
doesn't need to free the now static video_device structures,
hence, changed video_device.release in au0828_video_template
to point to video_device_release_empty.

Switch this driver over to the V4L2 core locking mechanism in preparation
for switching to unlocked_ioctl. Suggested by Laurent Pinchart.
This patch introduces a new mutex at the struct uvc_video level and
drops the old mutex at the queue level. The new lock is now used for all
ioctl locking and in the release file operation (the driver always has
to take care of locking in file operations, the core only serializes
ioctls).
Note that the mmap and get_unmapped_area file operations no longer take
a lock. Commit f035eb4e97 fixed a AB-BA
deadlock by moving all the locking down into vb2, so the mmap and
get_unmapped_area file operations should no longer do any locking before
calling into vb2.
