[MIPS] Ocelot C: Fix warning about missmatching format string.

  CC      arch/mips/momentum/ocelot_c/setup.o
arch/mips/momentum/ocelot_c/setup.c: In function 'momenco_time_init':
arch/mips/momentum/ocelot_c/setup.c:223: warning: format '%d' expects type 'int', but argument 2 has type 'long unsigned int'

Change data type to match format string; a 32-bit type better suits our
needs.
