ENGR00219859 MXC V4L2 capture:Pwr down/on opened cam
Currently, we support 2 cameras, which are relevant to
2 video devices respectively. This patch checks if video
device is opened to determine whether we need to power
down/on relevant camera when doing suspend/resume.
Also, this patch protects capture resources with busy
lock semaphore.
