It seems that the MPC107 is happy with 8 bit accesses to the registers,
so here's another version of the patch. This also changes the time
calculations to use time_after().

This still leaves the interrupt handling register of the MPC5200
unsolved. I suggest introducing another flag for the MPC5200, and adding
a small piece of extra setup code.
