drm/amd/display: Check for sharpening case when calculating max vtaps for scaler

Browse source

[Why & How]
- calc_lb_num_partitions has check when scaler is not enabled to use
 larger LB in calculations for max vtaps based on viewport being 1:1
- however, scaler is forced on when sharpening is enabled, so need
 to consider this in check
- taps is predetermined in spl_get_optimal_number_of_taps prior to
 calc_lb_num_partitions.  Add check for taps not 1 to handle
 sharpening case
