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

[Roland Dreier <rdreier@cisco.com>]

When adding the cputable entry for 440SPe Rev. B, we also need to
adjust the existing entries for 440SP Rev. A and 440SPe Rev. B so that
they look more bits of the PVR.  The 440SPe Rev. B has PVR 53421891,
which would match the current 440SP Rev. A pattern of 53xxx891.  To
distinguish between 440SP and 440SPe, we need to use the first three
digits of the PVR, which are respectively 532 and 534.

Here's a patch I've had for a while -- I think it may as well go in,
although I haven't had a chance to put much work into moving
Yucca/Katmai 440SPe support to arch/powerpc, so I'll probably miss
2.6.23 for the rest of it.
