Log Message:
Use panic stack temporarily for calling prom_printf in a trap
handler.

It seems that openfirmware cannot handle over 4GB pointers, and
stack pointers may point to over 4GB since VA layout was rearranged
by rev 1.33 of vmparam.h.  Therefore, use panic stack to avoid
panicking in OF_write used by prom_printf.
