When building arm32 allyesconfig,
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by freesync.c

>>> gpu/drm/amd/display/modules/freesync/freesync.o:(mod_freesync_build_vrr_params)
>>> in archive drivers/built-in.a
>>> did you mean: __aeabi_uidivmod
>>> defined in: arch/arm/lib/lib.a(lib1funcs.o)
Use div_u64 in the two locations that do 64-bit divisior, which both
have a u64 dividend and u32 divisor.
Fixes: 349a370781de ("drm/amd/display: LFC not working on 2.0x range monitors")
