[Qemu-devel] [PATCH] target-moxie: Fix VMState registration

[Peter Maydell <peter.maydell@linaro.org>]

Register the CPU VMState in the correct way, via cpu_class_set_vmsd(),
rather than doing it in two different wrong ways (once by providing
cpu_save and cpu_load functions, and once by setting the vmsd field in
DeviceClass).

Having just revamped the target-arm vmstate code I now have a
better grasp of how it should work, so I noticed we didn't quite
get moxie right. Not really very tested since I couldn't find a test
image to try, but should work better than the previous code...
