drm/amd/display: split TF/LUT colorop state lookups into separate upfront phases

Browse source

In __set_dm_plane_colorop_shaper and __set_dm_plane_colorop_blend the
single colorop_state variable was reused sequentially: first to capture
the TF state, then (after mutating the colorop pointer) to capture the
LUT state.

Split into separate tf_state / lut_state pointers and introduce a
dedicated lut_colorop local. Resolve both pointers upfront before any
computation begins. This separates the concern of "find the states" from
"use the states" and makes the code easier to follow.

No functional change.
