[Qemu-ppc] [PATCH 0/4] cuda/mos6522 migration fixes

[Mark Cave-Ayland]

Whilst performing a random migration test for the Mac machines I noticed
a regression (patch 1) which prevented the loadvm from completing
successfully. A big thank you to Peter and David on IRC who pointed me
in the right direction in order to fix the bug.

Once that was working I spent a bit more time analysing the migration
stream and realised that the mos6522 device state wasn't being embedded
within the CUDA device, but instead being maintained separately which is
solved by patch 2.

Patch 3 is something I noticed whilst rearranging the existing code based
upon my better understanding of QOM/qdev and ensures that the timer frequency
is always set correctly post-migration for the device and its parent class.
This leaves no remaining functionality in the mos6522 realize function and so
allows it to be removed.

Finally patch 4 was suggested by Peter on IRC whilst helping me investigate
the original migration issue, and removes the last remaining user of
VMSTATE_TIMER_PTR_TEST from the codebase.
