drm/amd/display: log MCM shaper and 3D LUT mode in the DTN log
On DCN4 the per-plane MCM shaper and 3D LUT state wasn't visible in the
DTN log: dcn401 wired read_mpcc_state to mpc1_read_mpcc_state, which only
reads the base MPCC blend registers, and the MPCC section didn't print the
LUT fields even where they were populated.
Add mpc401_read_mpcc_state to also read MPCC_MCM_3DLUT_MODE (mode current
and size) and MPCC_MCM_SHAPER_CONTROL (mode current), and print SHAPER,
3DLUT and 3DLUT_SIZE columns in the MPCC section. Mode is 0 bypass, 1
RAM_A, 2 RAM_B; 3DLUT_SIZE is 0 for 17x17x17 and 1 for 9x9x9.
