drm/amd/display: mark dml31's UseMinimumDCFCLK() as noinline_for_stack 

clang reports:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn31/display_mode_vba_31.c:3797:6: error: stack frame size (2632) exceeds limit (2048) in 'dml31_ModeSupportAndSystemConfigurationFull' [-Werror,-Wframe-larger-than]
 3797 | void dml31_ModeSupportAndSystemConfigurationFull(struct display_mode_lib *mode_lib)
      |      ^
1 error generated.

So, since UseMinimumDCFCLK() consumes a lot of stack space, mark it as
noinline_for_stack to prevent it from blowing up
dml31_ModeSupportAndSystemConfigurationFull()'s stack size.
