drm/amd/display: Update SPL Taps Required For Integer Scaling

Browse Source 
Number of taps is incorrectly being set when integer scaling is enabled.
Taps required when src_rect != dst_rect previously not considered.
Perform the calculations when integer scaling is enabled.
Set taps to 1 if the scaling ratio is 1:1.
