v4l2: use register_chrdev_region instead of register_chrdev
From: Hans Verkuil <hverkuil@xs4all.nl>
Replace the old register_chrdev with the more flexible register_chrdev_region.
Ensure that the release() is called when the very last chardev usage was
released, and not when the sysfs devices were removed. This should simplify
hotpluggable drivers considerably.
