drm/amd/display: Fix kernel docs for new struct members

[WHAT & HOW]
Add kernel-doc for new struct members for lut3d_caps and mpc_funcs.

This fixes the follow warnings from "make htmldocs".

./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:1106: warning: Function
parameter or struct member 'mcm' not described in 'mpc_funcs'
./drivers/gpu/drm/amd/display/dc/inc/hw/mpc.h:1106: warning: Function

./drivers/gpu/drm/amd/display/dc/dc.h:249: warning: Function parameter

./drivers/gpu/drm/amd/display/dc/dc.h:249: warning: Function parameter
or struct member 'preblend' not described in 'mpc_color_caps'
