* 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
