drm/amd/display: add back quality EASF and ISHARP and dc dependency changes

[Why]
Addressed previous issues with quality changes and new issues due to
 rolling back quality changes.

[How]
This reverts commit f9e67598, fixes merge conflicts, and fixed some
 formatting errors.
Store current sharpness level for each pregen table to minimize
 calculating sharpness table every time.
Disable dynamic ODM when sharpness is enabled.
