3a2c4d55e3 treewide: refresh kmalloc_obj() conversions
This is another run of the Coccinelle script for converting kmalloc()
family of allocations to kmalloc_obj() via the existing rules in
scripts/coccinelle/api/kmalloc_objs.cocci

This catches both the set of kmalloc() uses added since the first
kmalloc_obj() conversions in v7.0 and adds a large group missed in the
first pass due to Coccinelle not interacting well with the cleanup.h
scoped_...() family of macros[1]. I worked around this with spatch's
"--macro-file" argument to a file with all the scoped_...() macros mapped
to Coccinelle's YACFE_ITERATOR[2] as that was the closest viable control
flow indicator I could find.

Build tested allmodconfig on x86, arm64, arm, loongarch, mips, powerpc,
riscv, and s390 with no new warnings.

4195148325 drm/amd/display: Migrate color manager HW and fix MCM blend LUT issues
Combine two related color manager improvements:

1. Migrate MCM/RMCM, shaper and 3DLUT HW programming to dc_plane_cm
   - Continue convergence with upstream Color Manager refactor
   - Migrate MCM/RMCM, shaper and 3DLUT programming for dcn401+ to dc_plane_cm
   - Unify MCM programming across both legacy and 3DLUT DMA paths
   - Add 3DLUT DMA broadcast support for multi-pipe planes

2. Reprogram MCM blend LUT on blend_enable falling edge
   - Fix issue where SDR desktop remained desaturated after video playback
   - Detect blend_enable falling edge (1->0) in surface update detection
   - Force MCM LUT reprogramming on blend state change
