drm/amd/display: Respect CONFIG_FRAME_WARN=0 in DML2

display_mode_code.c is unconditionally built with
-Wframe-larger-than=2048, which causes warnings even when
CONFIG_FRAME_WARN has been set to 0, which should show no warnings.

Use the existing $(frame_warn_flag) variable, which handles this
situation. This is basically commit 25f178bbd078 ("drm/amd/display:
Respect CONFIG_FRAME_WARN=0 in dml Makefile") but for DML2.
