Subject: * sort the PowerPC target object files * make PowerPC NVRAM accessors
 generic to be able to use a MacIO NVRAM   instead of the M48T59 one * split
 PowerMac targets code:  - move all PowerMac related definitions and
 prototypes into hw/ppc_mac.h  - add hw/mac_dbdma.c, hw/mac_nvram.c and
 macio.c    which implements shared PowerMac devices  - define the g3bw
 machine in a new hw/ppc_oldworld.c file * Fix the g3bw target:  - fix the
 Grackle host PCI device  - connect the Heathrow PIC to the PowerPC 6xx bus
 pins
