For pSeries guest in QEMU, NVRAM is one kind of spapr-vio device.
Users are allowed to specify spapr-vio devices'address.
But NVRAM is not supported in libvirt. So this patch is to
add NVRAM device to allow users to specify its address.
In QEMU, NVRAM device's address is specified by
"-global spapr-nvram.reg=xxxxx".
In libvirt, XML file is defined as the following:
<nvram>
<address type='spapr-vio' reg='0x3000'/>
</nvram>

Currently, -device xxx still doesn't work well for ppc64 platform.
It's better use legacy USB option with default for ppc64.

To avoid the collision for creating USB controllers in machine->init()
and -device xx command line, it needs to set usb=off to avoid one USB
controller created in machine->init(). So that libvirt can use -device
or -usb to create USB controller sucessfully.
So QEMU_CAPS_MACHINE_USB_OPT capability is added, and it is for QEMU
v1.3.0 onwards which supports USB option.

Currently, -machine option is used only when dump-guest-core is set.
To use options defined in machine option for newer version of QEMU,
it needs to use -machine xxx, and to be compatible with older version
-M, this patch adds QEMU_CAPS_MACHINE_OPT capability for newer
version which supports -machine option.

When getting CPUs' information, it assumes that CPU indexes
are not contiguous. But for ppc64 platform, CPU indexes are not
contiguous because SMT is needed to be disabled, so CPU information
is not right on ppc64 and vpuinfo, vcpupin can't work corretly.
This patch is to remove the assumption to be compatible with ppc64.
Test:
4 vcpus are assigned to one VM and execute vcpuinfo command.
Without patch: There is only one vcpu informaion can be listed.
With patch: All vcpus' information can be listed correctly.

Currently, it only considers PTY backend serial devices for pseries.
It need to support all kinds of serial devices.
This patch is to fix the problem which is that it doesn't work
when specifying source type as file.

ACPI is only supported on x86 platform, PPC can't support it.
So QEMU_CAPS_NO_ACPI shouldn't be set.
This patch is to remove QEMU_CAPS_NO_ACPI capability for
non-x86 platform.

Historically, the first <console> element is treated as the
alias of a <serial> device. In the virDomainDeviceInfoIterate,
This situation is not considered. It still handles the first <console>
element as another devices, which means that for console[0] with
serial targetType, it calls callback function another time.
It will cause the problem of address conflicts when assigning
spapr-vio address for serial device on pSeries guest.
For pSeries guest, the serial configuration in the xml file
is as the following:
<serial type='pty'>
<target port='0'/>
<address type='spapr-vio'/>
</serial>
Console configuration is default, the dumped xml file is as the following:
<serial type='pty'>
<source path='/dev/pts/5'/>
<target port='0'/>
<alias name='serial0'/>
<address type='spapr-vio' reg='0x30000000'/>
</serial>
<console type='pty' tty='/dev/pts/5'>
<source path='/dev/pts/5'/>
<target type='serial' port='0'/>
<alias name='serial0'/>
<address type='spapr-vio' reg='0x30000000'/>
</console>
It shows that the <console> device is the alias of serial device.
So its address is the same as the serial device. When detecting
the conflicts in the qemuAssignSpaprVIOAddress the first console
and the serial device conflicts because virDomainDeviceInfoIterate()
still handle these as two different devices, and in the qemuAssignSpaprVIOAddress(),
it will compare these two devices' addressed. If they have same address,
it will report address conflict error.
So this patch is to handle the first console which targetType is serial
as the alias of serial device to avoid address conflicts error reported.

For pseries guest, spapr-vlan and spapr-vty is based
on spapr-vio address. According to model of network
device, the address type should be assigned automatically.
For serial device, serial pty device is recognized as
spapr-vty device, which is also on spapr-vio.
So this patch is to correct the address type of
spapr-vlan and spapr-vty, and build correct
command line of spapr-vty.

For pseries guest, the default controller model is
ibmvscsi controller, this controller only can work
on spapr-vio address.
This patch is to assign spapr-vio address type to
ibmvscsi controller and correct vscsi test case.
