Mac OS X's debugging serial driver accesses the ESCC through a different
register layout, called "escc-legacy". This layout differs from the normal
escc register layout purely by the location of the respective registers.

This patch adds a memory alias region that takes normal escc registers and
maps them into the escc-legacy register space.

With this patch applied, a Mac OS X guest successfully emits debug output
on the serial port when run with debug parameters set, for example by running:

  $ qemu-system-ppc -prom-env -'boot-args=-v debug=0x8 io=0xff serial=0x3' \
                    -cdrom 10.4.iso -boot d

cppcheck detected a condition which was always false.

According to the MCIMX31 Reference Manual, the PRCS bits have to be 01
to select the Frequency Pre-Multiplier (FPM). PRCS uses bits 1 and 2,
so we have to test for 2.

So far, the size of all regions passed to listeners could fit in 64 bits,
because artificial regions (containers and aliases) are eliminated by
the memory core, leaving only device regions which have reasonable sizes

An IOMMU however cannot be eliminated by the memory core, and may have
an artificial size, hence we may need 65 bits to represent its size.

If the user fails to specify 'chardev' or 'shm' then we cannot continue.
Exit right away so that we don't invoke shm_open(3) with a NULL pointer.

It would be nice to replace exit(1) with error returns in the PCI device
.init() function, but leave that for another patch since exit(1) is
currently used elsewhere.

pvpanic device is used to send guest panic event from guest to qemu.

When guest panic happens, pvpanic device driver will write a event
number to IO port 0x505(which is the IO port occupied by pvpanic device,
by default). On receiving the event, pvpanic device will pause guest
cpu(s), and send a qmp event QEVENT_GUEST_PANICKED.
