drm/amd/display: ensure EASF and ISHARP coefficients are programmed together

drm/amd/display: ensure EASF and ISHARP coefficients are programmed together

[Why]
EASF coefficients are programmed to RAM and then RAM selector is toggled.
 ISHARP coefficients are programmed after so they will not be in the same
 RAM block

[How]
Move ISHARP programming before EASF programming
Add flag if ISHARP coefficients are updated.  If so, then
 force EASF coefficients programming
