this could go as fix into 4.2 please.

With what is currently in 4.2-rc3 I'm loosing the mouse cursor in my xf86-
armsoc xserver [0]. Likely due to 0915da7dd75f ("drm/rockchip: vop: remove 
hardware cursor window"). The xserver then selects a window for the cursor 
itself, which seems to be one of the currently disabled ones.

This patch fixes this and gives me back my cursor :-)
