[media] v4l: vsp1: uds: Enable scaling of alpha layer

Browse Source 
Scaling of the alpha layer is disabled as both the RPF and WPF are
configured to hardcode the alpha value to 255. This results in a 0 alpha
value at the UDS output, making the image invisible when alpha blended
in the BRU. Fix it by enabling scaling of the alpha layer.
