fbdev: dpu: shadow register update request method is modified.

In DPU common driver, shadow register update request was configured in
order for the used winodw only. However, in this case, if vsync occurs
during windows setup, only shadow register update request windows can be
shadow update.
 So, shadow register update request method is modified to make shdadow
update requests for all windows at once.
