drm/amd/display: fix compilation error due to shifting negative value
Currently compiling linux-next with allmodconfig triggers the following error: ./drivers/gpu/drm/amd/amdgpu/../display/include/fixed31_32.h: In function ‘dc_fixpt_truncate’: ./drivers/gpu/drm/amd/amdgpu/../display/include/fixed31_32.h:528:22: error: left shift of negative value [-Werror=shift-negative-value] 528 | arg.value &= (~0LL) << (FIXED31_32_BITS_PER_FRACTIONAL_PART - frac_bits); | ^~ Use `unsigned long long` instead.
