[RFC] ppc32: Report chip version in common /proc/cpuinfo handling

[Kumar Gala]

Tom,

You asked me to look at doing the following.  I just want to make sure 
this is what we want to do (and call it).  I'm a little concerned that 
'chip' is not necessary the right name in light of TSI10x and MV64x60 
being described by ppc_sys in the future.

Moved reporting of chip revision from board specific to common handing of 
/proc/cpuinfo.  In light of numerous PPC system-on-chip devices, we report 
both the cpu version (reflects the core version) and the chip version 
(reflects the system-on-chip version).
