[PATCH] IBM PowerPC 750GX Support

[Bryan Rittmeyer]

This patch adds preliminary support for the IBM PowerPC 750GX. In
summary this part is a PPC750FX ramped to 1 GHz with a 1MB 4-way L2
and more advanced I/O pipelining. It is beginning to appear in embedded
systems and was rumored to be under evaluation inside Apple. Tested on
PVR 70020101; please merge.
