linux/v4l2-compliance: support to modprobe driver and install v4l-utils

* Add hikey to supported board list.
* Add support to modprobe driver module.
* Try to install v4l-utils when v4l2-compliance command not found.
* Drop support for media device testing as we cannot really test it.
* Bug fixes.
