mlxsw: spectrum_cnt: Fix 64-bit division in mlxsw_sp_counter_resources_register

Browse Source 
When building arm32 allyesconfig:

ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by spectrum_cnt.c
>>>               net/ethernet/mellanox/mlxsw/spectrum_cnt.o:(mlxsw_sp_counter_resources_register) in archive drivers/built-in.a
>>> did you mean: __aeabi_uidivmod
>>> defined in: arch/arm/lib/lib.a(lib1funcs.o)

pool_size and bank_size are u64; use div64_u64 so that 32-bit platforms
do not error.
