[PATCH] [POWERPC] Add cputable entry for PowerPC 440SPe Rev. B

Add a cputable entry for revision B of the AMCC 440SPe.  When adding
this entry, we need to adjust the entry for 440SP Rev. A so that it
matches more bits of the PVR, since the 440SPe Rev. B has PVR
53421891, which would match the old 440SP PVR pattern of 53xxx891.

I'm still working on cleaning up the PCI Express changes for 440SPe
Rev. B support but I think we might as well queue this up at least.

I haven't heard from Matt in a while so maybe you could pick this up
directly Paul?

Thanks,
  Roland

Is Rev. B the one found on the AMCC Katmai board?

I would guess so -- it's the current rev.

I don't have a katmai board (just a yucca reworked with a rev. b chip)

Ok.  I'm supposedly getting a 440SPe board soon, so I guess I'll find
out soon enough.
