What about ppc_plat_xxx() or ppc_sys_xxx() [for system]?  'sys' maybe 
more consistent with our naming conventions in that arch/ppc/platforms 
is more board focused, and arch/ppc/syslib is bridge and non-core chip 
functionality.

This is problematic for some things like the updating of the IOMEM 
resources since that needs to occur before platform_device_register is 
called.  However, the updates in mpc8540_ads.c could possibly handled 
by platform_notify(), will look into that.
