This seems to break vop initialization on my rk3036 kylin board.
Before, kylin was able to bring output to the hdmi but with this
patch applied this stops working. As the init-value is to zero it seems
there is still something turned on, that should be turned off instead.
rk3288 seems to stay in working condition though.
