drm/amd/display: Use pixels per container logic for DCN314 DCCG dividers

Browse Source 
[Why]
DP DSC YCbCr422 not working because dcn314_calculate_dccg_k1_k2_values
does not account for two pixels per container

[How]
Replace the contents of dcn314_calculate_dccg_k1_k2_values with the
code from the function dcn32_calculate_dccg_k1_k2_values
