Now that we have implemented PAPR compatible NVRAM interfaces in qemu, this
updates the SLOF firmware to actually initialize and use the NVRAM as a
PAPR guest firmware is expected to do.
This SLOF update also includes an ugly but useful workaround for a bug in
the SLES11 installer which caused it to fail under KVM.

Currently on the pseries machine the SLOF firmware is used normally,
but we bypass it when -kernel is specified. Having these two
different boot paths can cause some confusion.
In particular at present we need to "probe" the (emulated) PCI bus and
produce device tree nodes for the PCI devices in qemu, for the -kernel
case. In the SLOF case, it takes the device tree from qemu adds some
stuff to it then passes it on to the kernel.
It's been decided that a better approach is to always boot through
SLOF, even when using -kernel. WIth this approach we can leave PCI
probing and device node creation to SLOF in all cases which removes a
bunch of code in qemu, and avoids iterating the PCI devices from the
machine specific init code which we're not supposed to do.
This patch changes qemu to always boot through SLOF, and not to create
PCI nodes. Simultaneously it updates the included version of SLOF
(submodule and binary image) to one which supports (and requires) the
new approach.
The new SLOF version also includes a number of unrelated enhancements:
support for booting from virtio-pci devices and e1000, greatly
improved FCode support and many bugfixes. It also makes SLOF ready to
be used even when specifying a kernel on the qemu command line.

This patch updates the SLOF submodule and precompiled image. The new
SLOF versions contains two changes of note:
* The previous SLOF has a bug in SCSI condition handling that was
exposed by recent updates to qemu's SCSI emulation. This update
fixes the bug.
* The previous SLOF has a bug in its addressing of SCSI devices,
which can be exposed under certain conditions. The new SLOF also
fixes this.

Currently, the emulated pSeries machine requires the use of the
-kernel parameter in order to explicitly load a guest kernel. This
means booting from the virtual disk, cdrom or network is not possible.
This patch addresses this limitation by inserting a within-partition
firmware image (derived from the "SLOF" free Open Firmware project).
If -kernel is not specified, qemu will now load the SLOF image, which
has access to the qemu boot device list through the device tree, and
can boot from any of the usual virtual devices.
In order to support the new firmware, an extension to the emulated
machine/hypervisor is necessary. Unlike Linux, which expects
multi-CPU entry to be handled kexec() style, the SLOF firmware expects
only one CPU to be active at entry, and to use a hypervisor RTAS
method to enable the other CPUs one by one.
This patch also implements this 'start-cpu' method, so that SLOF can
start the secondary CPUs and marshal them into the kexec() holding
pattern ready for entry into the guest OS. Linux should, and in the
future might directly use the start-cpu method to enable initially
disabled CPUs, but for now it does require kexec() entry.

This patch adds a firmware blob to the S390 target. The blob is a simple
implementation of a virtio client that tries to read the second stage
bootloader from sectors described as of offset 0x20 in the MBR.
In combination with an updated zipl this allows for booting from virtio
block devices. This firmware is built from the same sources as the second
stage bootloader. You can find a virtio capable s390-tools in this repo:

Only two boot ROM files are needed for all devices.
* Add these GPXE ROM files using new naming convention
(as discussed on qemu-devel). Both files were created
with http://rom-o-matic.net/, PCI vendor / device ids
as in ROM filenames and option BANNER_TIMEOUT = 0.
* Remove old PXE ROM file for i82559er.
It was replaced by gpxe-eepro100-80861209.rom.
* Update pc-bios/README (and sort entries).
