qdev: DEVICE_DELETED event

libvirt has a long-standing bug: when removing the device,
it can request removal but does not know when the
removal completes. Add an event so we can fix this in a robust way.

target-lm32: fix debug memory access

CPU models which have the LM32_FLAG_IGNORE_MSB flag set will shadow the
lower 2GB to the upper 2GB memory space. This will fix the debug memory
access used by qemu console and GDB to match this behaviour.

pseries: Fix breakage in CPU QOM conversion

Commit 259186a7d2f7184efc96ae99bc5658e6159f53ad "cpu: Move halted and
interrupt_request fields to CPUState" broke the pseries machine.  That's
because it uses CPU() instead of ENV_GET_CPU() to convert from the global
first_cpu pointer (still a CPUArchState) to a CPUState.  This patch fixes
the breakage.

pseries: Remove "busname" property for PCI host bridge

Currently the "spapr-pci-host-bridge" device has a "busname" property which
can be used to override the default assignment of qbus names for the bus
subordinate to the PHB.  We use that for the default primary PCI bus, to
make libvirt happy, which expects there to be a bus named simply "pci".
The default qdev core logic would name the bus "pci.0", and the pseries
code would otherwise name it "pci@800000020000000" which is the name it
is given in the device tree based on its BUID.

The "busname" property is rather clunky though, so this patch simplifies
things by just using a special case hack for the default PHB, setting
busname to "pci" when index=0.

target-ppc: Remove CONFIG_PSERIES dependency in kvm.c

target-ppc/kvm.c has an #ifdef on CONFIG_PSERIES, for the handling of
KVM exits due to a PAPR hypercall from the guest.  However, since commit
e4c8b28cde12d01ada8fe869567dc5717a2dfcb7 "ppc: express FDT dependency of
pSeries and e500 boards via default-configs/", this hasn't worked properly.
That patch altered the configuration setup so that although CONFIG_PSERIES
is visible from the Makefiles, it is not visible from C files.  This broke
the pseries machine when KVM is in use.

This patch makes a quick and dirty fix, by removing the CONFIG_PSERIES
dependency, replacing it with TARGET_PPC64 (since removing it entirely
leads to type mismatch errors).  Technically this breaks the build when
configured with --disable-fdt, since that disables CONFIG_PSERIES on
TARGET_PPC64.  However, it turns out the build was already broken in that
case, so this fixes pseries kvm without breaking anything extra.  I'm
looking into how to fix that build breakage, but I don't think that need
delay applying this patch.

pseries: Move XICS initialization before cpu initialization

Currently, the pseries machine initializes the cpus, then the XICS
interrupt controller.  However, to support the upcoming in-kernel XICS
implementation we will need to initialize the irq controller before the
vcpus.  This patch makes the necesssary rearrangement.  This means the
xics init code can no longer auto-detect the number of cpus ("interrupt
servers" in XICS terminology) and so we must pass that in explicitly from
the platform code.
