drm/amd/display: fix __udivdi3 link error

When compiling the AMDGPU display driver for 32-bit architectures,
the linker reports undefined reference to `__udivdi3` in functions
get_dp_dto_frequency_100hz() and dcn401_get_dp_dto_frequency_100hz().

This is because the code uses 64-bit division (/) on 32-bit systems,
which GCC cannot handle directly and instead tries to call the missing
__udivdi3 helper function.

Replace the raw division with div_u64(), the kernel's standard 64-bit
division helper, to avoid the link error.
