[PATCH 14/16] drm/amd/display: store sharpness 1dlut table in dscl_prog_data

[Tom Chung]

From: Samson Tam <Samson.Tam at amd.com>

[Why]
Previously dscl_prog_data stored pointer to sharpness 1dlut table.
SPL had four pre-generated tables, one for each setup. This allowed
us to minimize number of times we had to recalculate table when
switching between setups.
However, with dual display, this becomes an issue because for a given
setup, we could have a different per app sharpness value than the
global sharpness value. So the pre-generated table will change
but both displays may point to the same table and one of them
will have the wrong sharpness setting.

[How]
Store the sharpness 1dlut table in dscl_prog_data. This ensures
that each display can have its own sharpness setting.
