When building arm32 allyesconfig:
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by dc_link.c
>>> gpu/drm/amd/display/dc/core/dc_link.o:(wait_for_alt_mode) in archive drivers/built-in.a
>>> referenced by dc_link.c
>>> gpu/drm/amd/display/dc/core/dc_link.o:(wait_for_alt_mode) in archive drivers/built-in.a
time_taken_in_ns is of type unsigned long long so we need to use div_u64
to avoid this error.
Fixes: b5b1f4554904 ("drm/amd/display: Enable type C hotplug")
