VBLANK interrupts can be disabled immediately or with a delay, where the latter is the default. The former option can be selected by setting get_vblank_timestamp and enabling vblank_disable_immediate in struct drm_device. Simplify the code in preparation of the removal of struct drm_device.get_vblank_timestamp.
v3: * remove internal setup of vblank_disable_immediate
