avoid having to test again for MIPS32R2 instructions. Keep the shift

spapr-pci: rework MSI/MSIX
On the sPAPR platform a guest allocates MSI/MSIX vectors via RTAS
hypercalls which return global IRQ numbers to a guest so it only
operates with those and never touches MSIMessage.
Therefore MSIMessage handling is completely hidden in QEMU.
Previously every sPAPR PCI host bridge implemented its own MSI window
to catch msi_notify()/msix_notify() calls from QEMU devices (virtio-pci
or vfio) and route them to the guest via qemu_pulse_irq().
MSIMessage used to be encoded as:
.addr - address within the PHB MSI window;
.data - the device index on PHB plus vector number.
The MSI MR write function translated this MSIMessage to a global IRQ
number and called qemu_pulse_irq().
However the total number of IRQs is not really big (at the moment it is
1024 IRQs starting from 4096) and even 16bit data field of MSIMessage
seems to be enough to store an IRQ number there.
This simplifies MSI handling in sPAPR PHB. Specifically, this does:
1. remove a MSI window from a PHB;
2. add a single memory region for all MSIs to sPAPREnvironment
and spapr_pci_msi_init() to initialize it;
3. encode MSIMessage as:
* .addr - a fixed address of SPAPR_PCI_MSI_WINDOW==0x40000000000ULL;
* .data as an IRQ number.
4. change IRQ allocator to align first IRQ number in a block for MSI.
MSI uses lower bits to specify the vector number so the first IRQ has to
be aligned. MSIX does not need any special allocator though.

pseries: Fix stalls on hypervisor virtual console
A number of users are reporting stalls when using the pseries
hypervisor virtual console.
A simple test case is to paste 15 or 17 characters at a time
into the console. Pasting 15 characters at a time works fine
but pasting 17 characters hangs for a random amount of time.
Other activity (network, qemu monitor etc) unblocks it.
If qemu-char tries to send more than 16 characters at once,
vty_can_receive returns false. At this point we have to
wait for the guest to consume that output. Everything is good
so far.
The problem occurs when the the guest does consume the output.
We need to signal back to the qemu-char layer that we are
ready for more input. Without this we block until something
else kicks us (eg network activity).

PPC: E500: Generate device tree on reset
Today we generate the device tree once on machine initialization and then
store the finalized blob in memory to reload it on reset.
This is bad for 2 reasons. First we potentially waste a bunch of RAM for no
good reason, as we have all information required to regenerate the device
tree available anyways.
The second reason is even more important. On machine init when we generate
the device tree for the first time, we don't have all of the devices fully
initialized yet. But the device tree needs to potentially walk devices to
put information about them into the device tree.
Move the generation into a reset function. That way we just generate it new
every time we reset, solving both of the above issues.

pc: reduce duplication, fix PIIX descriptions
We have a lot of code duplication between machine types,

This has already introduced a minor bug: description

pc-1.4 is "Standard PC (i440FX + PIIX, 1996)"

s390: wire up nmi command to raise a RESTART interrupt on S390
There is the 'nmi' command that is used to trigger a guest dump via kdump feature on x86.
s390 uses RESTART interrupt to trigger kdump.
So, this patch provides a mean to use 'nmi' command on s390 to raise RESTART interrupt.
The CPU to receive the RESTART interrupt is the "default" one.
There is an infrastructure to select the "default" CPU using 'cpu' command.
The 'info cpus' command can be used to see which one is the "default".
In order to wire up the RESTART to 'nmi' command we had to:
1. implement the kvm_s390_cpu_restart function by exporting the existing code
2. implement s390_cpu_restart function as kvm-aware wrapper
3. modify the qmp_inject_nmi function to enable (for s390) the scan for
"default" CPU and call s390_cpu_restart for it;
3. fix some messages.

The old code in help_cmd() uses global 'info_cmds' and treats it as a
special case. Actually 'info_cmds' is a sub command group of 'mon_cmds',
in order to avoid direct use of it, help_cmd() needs to change its work
mechanism to support sub command and not treat it as a special case
any more.
To support sub command, help_cmd() will first parse the input and then call
help_cmd_dump(), which works as a reentrant function. When it meets a sub
command, it simply enters the function again. Since help dumping needs to
know whole input to printf full help message include prefix, for example,
"help info block" need to printf prefix "info", so help_cmd_dump() takes all
args from input and extra parameter arg_index to identify the progress.
Another function help_cmd_dump_one() is introduced to printf the prefix
and command's help message.
Now help supports sub command, so later if another sub command group is
added in any depth, help will automatically work for it. Still "help info
block" will show error since command parser reject additional parameter,
which can be improved later. "log" is still treated as a special case.
