Subject: [PATCH 2/2] drm/amd/display: Fix CFLAGS for dml2_core_dcn4_calcs.o

-Wframe-larger-than=2048 is a part of both CFLAGS and CFLAGS_REMOVE for
dml2_core_dcn4_calcs.o, which means that it ultimately gets removed
altogether for 64-bit targets, as 2048 is the default FRAME_WARN value
for 64-bit platforms, resulting in no -Wframe-larger-than coverage for
this file.

Remove -Wframe-larger-than from CFLAGS_REMOVE_dml2_core_dcn4_calcs.o and
move to $(frame_warn_flag) for CFLAGS_dml2_core_dcn4_calcs.o, as that
accounts for the fact that -Wframe-larger-than may need to be larger
than 2048 in certain situations, such as when the sanitizers are
enabled.
