[PATCH] drm/amd/display: Initialize missing TD-LUT programming inputs

[Avi Weiss <thnkslprpt@gmail.com>]

dml_core_mode_programming() memsets (clears) its scratch structure
before calculating TD-LUT settings, but does not initialize
tdlut_mpc_width_flag or is_gfx11.

Both inputs therefore remain false regardless of the plane
configuration which can result in incorrect calculations.

Initialize both fields using the same sources as the mode
support path (now both paths are aligned).

Fixes: 70839da63605 ("drm/amd/display: Add new DCN401 sources")
