mlxsw: Fix 64-bit division in mlxsw_sp_sb_prs_init
When building for 32-bit ARM, there is a link time error because of a
64-bit division:
ld.lld: error: undefined symbol: __aeabi_uldivmod
>>> referenced by spectrum_buffers.c
>>> net/ethernet/mellanox/mlxsw/spectrum_buffers.o:(mlxsw_sp_buffers_init) in archive drivers/built-in.a
>>> did you mean: __aeabi_uidivmod
>>> defined in: arch/arm/lib/lib.a(lib1funcs.o
Avoid this by using div_u64, which is designed to avoid this problem.
Fixes: bc9f6e94bcb5 ("mlxsw: spectrum_buffers: Calculate the size of the main pool")
