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