drm/amd/display: Fill prescale_params->scale for RGB565
[Why]
An assertion is thrown when using SURFACE_PIXEL_FORMAT_GRPH_RGB565
formats on DCE since the prescale_params->scale wasn't being filled.
Found by a dmesg-fail when running the
igt@kms_plane@pixel-format-pipe-a-planes test on Baffin.
[How]
Fill in the scale parameter.
