drm/amd/display: quality improvements for EASF and ISHARP
[Why]
Update coefficients and LUT tables for scaler and sharpener
to improve quality and support different use cases (SDR/HDR)
[How]
Move scaler coefficients to new file dc_spl_scl_easf_filters.c
Remove older coefficients file dc_sp_scl_filters_old.c
Update default taps for EASF support
Update LLS policy for DON'T CARE case
Update cositing offset from 0.5 to 0.25
Add support to adjust sharpness based on level, use case,
and scaling ratio ( using discrete levels )
Apply sharpness to all RGB surfaces and both NV12 and P010
video ( in fullscreen only ). Upscale and 1:1 ratios only
Enable scaler when sharpening 1:1 ratios
Add support for coefficients that are in S1.10 format
(convert to S1.12 format)
