Besides the new value in the version register, this provides:
- ILR support, which includes:
- IDR becoming a pure CPU bitmap, allowing 32 CPUs
- machine check output support (though other parts of QEMU need to
be fixed for it to do something other than immediately reboot the
guest)
- dummy error interrupt support (EISR0/EIMR0 read as zero)
- actually all FSL MPICs get all summary registers returning zero for now,
which includes EISR0/EIMR0
Various refactoring is done to support these changes and to ease
new functionality (e.g. a more flexible way of declaring regions).
Just as the code was already not a full implementation of MPIC v2.0,
this is not a full implementation of MPIC v4.2 -- e.g. it still has only
one bank of MSIs.

This patch converts the OpenPIC device to qdev. Along the way it
renames the "openpic" target to "raven" and the "mpic" target to
"fsl_mpic_20", to better reflect the actual models they implement.
This way we have a generic OpenPIC device now that can handle
different flavors of the OpenPIC specification.

The current openpic emulation contains half-ready code for bypass mode.
Remove it, so that when someone wants to finish it they can start from a
clean state.

The IRQ raise mechanisms of the OpenPIC and MPIC controllers is identical,
just that the MPIC one can also raise critical interrupts.
Combine those two and check for critical raise capability during runtime.

target_phys_addr_t is unwieldly, violates the C standard (_t suffixes are
reserved) and its purpose doesn't match the name (most target_phys_addr_t
addresses are not target specific). Replace it with a finger-friendly,
standards conformant hwaddr.
Outstanding patchsets can be fixed up with the command
git rebase -i --exec 'find -name "*.[ch]"
| xargs s/target_phys_addr_t/hwaddr/g' origin

bus is always NULL so the code in this if clause is dead (and therefore
untested).

This patch converts mpic to the new memory API (through old mmio).

In the very least, a change like this requires discussion on the list.
The naming convention is goofy and it causes a massive merge problem. Something
like this _must_ be presented on the list first so people can provide input
and cope with it.
This reverts commit 99a0949b720a0936da2052cb9a46db04ffc6db29.

Some not so obvious bits, slirp and Xen were left alone for the time
being.

MPIC and OpenPIC have very similar design.
So a lot of code can be reused.
