drm/amd/display: Apply e4479aecf658 to dml

[ Upstream commit 70740454377f1ba3ff32f5df4acd965db99d055b ]

After an innocuous optimization change in clang-22, allmodconfig (which
enables CONFIG_KASAN and CONFIG_WERROR) breaks with:

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c:1724:6: error: stack frame size (3144) exceeds limit (3072) in 'dml32_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
   1724 | void dml32_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
        |      ^

With clang-21, this function was already pretty close to the existing
limit of 3072 bytes.

  drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c:1724:6: error: stack frame size (2904) exceeds limit (2048) in 'dml32_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
   1724 | void dml32_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
        |      ^

A similar situation occurred in dml2, which was resolved by
commit e4479aecf658 ("drm/amd/display: Increase sanitizer frame larger
than limit when compile testing with clang") by increasing the limit for
clang when compile testing with certain sanitizer enabled, so that
allmodconfig (an easy testing target) continues to work.

Apply that same change to the dml folder to clear up the warning for
allmodconfig, unbreaking the build.
