cris: move usec/nsec conversion to do_slow_gettimeoffset

Browse source 
Move usec to nsec conversion from arch_gettimeoffset() to
do_slow_gettimeoffset(); in a future patch, do_slow_gettimeoffset()
will be used directly as the implementation of arch_gettimeoffset(),
so needs to perform all required calculations.
