drm/amd/display: 3DLUT non-DMA refactor

Browse source

[Why]
Currently the handling for 3DLUT is found in multiple different
places, which causes issues when the different functions are not
in sync with each other.
Frequently bugs occur because the LUT handling is broken up, and
what has already been handled isn't kept track of well, which can
cause earlier changes to the LUT params to be overridden.

[How]
Remove DMA LUT handling from DCN401 and refactor legacy LUT
handling in one place to make it easier to keep track of what has
and needs to be done.
