Copy SPRG0-3 registers at boot-time and restore when calling into
OpenFirmware. FreeBSD/ppc uses SPRG0 as the per-cpu data area pointer,
and SPRG1-3 as temporary registers during exception handling. There
have been a few instances where OpenFirmware does require these to
be part of it's context, such as cd-booting an eMac.
