i2c: mlxbf: avoid 64-bit division
The 64-bit division in mlxbf_i2c_get_ticks() causes link failures
when compile-testing on 32-bit machines:
ERROR: modpost: "__udivdi3" [drivers/i2c/busses/i2c-mlxbf.ko] undefined!
Change this to a div_u64(), which should replace the constant division
with a a multiply/shift combination in the mlxbf_i2c_get_ticks().
The frequency calculation functions require a slow library call but
should be used much rarer.
