[Qemu-ppc] [PATCHv2 0/1] net: Add SunGEM device emulation as found on Apple UniNorth

[Mark Cave-Ayland]

This is a reworking of Ben's original implementation of the SunGEM device
from last year: 
https://lists.gnu.org/archive/html/qemu-devel/2016-08/msg02571.html.

The reason for implenting this device is that it allows out-of-the-box
networking for most MacOS 9 and MacOS X OSs running under qemu-system-ppc 
without
having to obtain any external vendor drivers.

The main changes I've made to Ben's original patch are listed below:
    - Remove sungem.h file, moving constants into sungem.c as required
    - Switch to using tracepoints for debugging
    - Split register blocks into separate memory regions
    - Use arrays in SunGEMState to hold register values
    - Add state-saving support

v2
- Fix tracepoints for trace backends outside of QEMU
- Introduce PCI_BASE_ADDRESS_SPACE_MEMORY instead of using the value 0 directly
