mlxsw: spectrum_ptp: Fix compilation on 32-bit ARM
Compilation on 32-bit ARM fails after commit 992aa864dca0 ("mlxsw:
spectrum_ptp: Add implementation for physical hardware clock operations")
because of 64-bit division:
arm-linux-gnueabi-ld:
drivers/net/ethernet/mellanox/mlxsw/spectrum_ptp.o: in function
`mlxsw_sp1_ptp_phc_settime': spectrum_ptp.c:(.text+0x39c): undefined
reference to `__aeabi_uldivmod'
Fix by using div_u64().
Fixes: 992aa864dca0 ("mlxsw: spectrum_ptp: Add implementation for physical hardware clock operations")
