drm/amdgpu/display: reduce stack size in dml32_ModeSupportAndSystemConfigurationFull()

Move more stack variable in to dummy vars structure on the heap.

Fixes stack frame size errors:
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c: In function 'dml32_ModeSupportAndSystemConfigurationFull':
drivers/gpu/drm/amd/amdgpu/../display/dc/dml/dcn32/display_mode_vba_32.c:3833:1: error: the frame size of 2720 bytes is larger than 2048 bytes [-Werror=frame-larger-than=]
 3833 | } // ModeSupportAndSystemConfigurationFull
      | ^
