Louis Kuo e6a59da61e ANDROID: media: v4l2-core: Fix deadlock in vendor hook ...

The vendor hook functions we implemented will invoke callback functions which have do some sleep or spinlock
operations and have risk of deadlock due to preemption disabled of normal vendor hook function.
So we have to use restricted vendor hook function instead.
Due to KMI freeze we could not change the existing hooks.

trace_android_rvh_media_device_setup_link	=>invoke setup_link, link_notify callback
trace_android_rvh_v4l2subdev_set_xxx		=>invoke set_xxx callback
