drm/msm/dpu: Fix scale params in plane validation
Plane validation uses an API drm_calc_scale which will
return src/dst value as a scale ratio.
when viewing the range on a scale the values should fall in as
Upscale ratio < Unity scale < Downscale ratio for src/dst formula
Fix the min and max scale ratios to suit the API accordingly.
