drm/amd/display: Fix __floatunsidf undefined for 32 bit compilation
When we tried to compile DCN32/321 for 32-bit architecture, we got this
error message:
ERROR: modpost: "__floatunsidf" [drivers/gpu/drm/amd/amdgpu/amdgpu.ko] undefined!
This was caused because we were trying to assign an unsigned int to a
double value which causes issues for 32-bit architecture. This issue can
be fixed by changing the value type.
