video: driver: amend xo reset clock as shared resource

Bläddra i källkod 
Use devm_reset_control_get_exclusive_released() instead of
devm_reset_control_get() to get the reset control of video_xo_reset
clock as it is shared reset clock between eva and video drivers.
Use reset_control_acquire() before assert and reset_control_release()
after de-assert video_xo_reset clock to avoid eva driver operating on
it in parallel.
