spapr-rtas: add CPU argument to RTAS calls

RTAS is a hypervisor provided binary blob that a guest loads and
calls into to execute certain functions. It's similar to the
vsyscall page in Linux or the short lived VMCI paravirt interface
from VMware.

The QEMU implementation of the RTAS blob is simply a passthrough...

dma: eliminate DMAContext

The DMAContext is a simple pointer to an AddressSpace that is now always
already available. Make everyone hold the address space directly,
and clean up the DMA API to use the AddressSpace directly.

memory: give name to every AddressSpace

The "info mtree" command in QEMU console prints only "memory" and "I/O"
address spaces while there are actually a lot more other AddressSpace
structs created by PCI and VIO devices. Those devices do not normally
have names and therefore not present in "info mtree" output....

spapr_vio: take care of creating our own AddressSpace/DMAContext

Fetch the root region from the sPAPRTCETable, and use it to build
an AddressSpace and DMAContext.

Now, everywhere we have a DMAContext we also have access to the
corresponding AddressSpace (either because we create it just before...

spapr: convert TCE API to use an opaque type

The TCE table is currently returned as a DMAContext, and non-type-safe
APIs are called later passing back the DMAContext. Since we want to move
away from DMAContext, use an opaque type instead, and add an accessor...

ppc: Remove CONFIG_FDT conditionals

Now that we know we're compiling with libfdt we can remove the
CONFIG_FDT conditionals.

pseries: Generate device paths for VIO devices

This patch implements a get_dev_path qdev hook for the pseries paravirtual
VIO bus. With upcoming savevm support, this will become very important for
scsi disks hanging of VIO virtual SCSI adapters. scsibus_get_dev_path...

pseries: Convert VIO code to QOM style type safe(ish) casts

Curerntly the pseries VIO device code contains quite a few explicit
uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe,
and not the conventional way of doing things in the QOM model. This...

hw: move headers to include/

Many of these should be cleaned up with proper qdev-/QOM-ification.
Right now there are many catch-all headers in include/hw/ARCH depending
on cpu.h, and this makes it necessary to compile these files per-target.
However, fixing this does not belong in these patches....
