xics: convert init() to realize()

This fixes XICS according new QOM rules.

This converts ICS's init() callbacks to realize().

This converts legacy qdev_init_nofail() to property_set(realized).

xics: split to xics and xics-common

The upcoming XICS-KVM support will use bits of emulated XICS code.
So this introduces new level of hierarchy - "xics-common" class. Both
emulated XICS and XICS-KVM will inherit from it and override class
callbacks when required....

xics: add cpu_setup callback

This adds a cpu_setup callback to the XICS device class (as XICS-KVM
will do it different), xics_cpu_setup() will call it if it is set.

xics-kvm: Support for in-kernel XICS interrupt controller

Recent (host) kernels support emulating the PAPR defined "XICS" interrupt
controller system within KVM. This patch allows qemu to initialize and
configure the in-kernel XICS, and keep its state in sync with qemu's XICS...

xics: Implement H_IPOLL

This adds support for the H_IPOLL hypercall which the guest
uses to poll for a pending interrupt. This hypercall is
mandatory for PAPR+ and there is no way for the guest to
detect whether it is supported or not so just add it.

xics: Implement H_XIRR_X

This implements H_XIRR_X hypercall in addition to H_XIRR as
it is mandatory for PAPR+ and there is no way for the guest to
detect whether it is supported or not so just add it.

As the Partition Adjunct Option is not supported at the moment,...

xics-kvm: enable irqfd for MSI

This enables IRQFD support for sPAPR. The feature decreases the latency
of interrupt handling.

To enable IRQFD for MSI, this sets kvm_gsi_direct_mapping to true which
enables direct MSI mapping.

To enable IRQFD for LSI (level triggered INTx interrupts), a PCI host bus...
