Construction of the /vdevice node (and its children) is divided between
spapr_create_fdt_skel() (at init time), which creates the base node, and
spapr_populate_vdevice() (at reset time) which creates the nodes for each
individual virtual device.
This consolidates both into a single function called from
spapr_build_fdt().

For historical reasons, building the /chosen node in the guest device tree
is split across several places and includes both parts which write the DT
sequentially and others which use random access functions.
This patch consolidates construction of the node into one place, using
random access functions throughout.

The original QOMification of the spapr VIO devices in 3954d33 "spapr:
convert to QEMU Object Model (v2)" moved some callbacks from the
VIOsPAPRBus structure to the VIOsPAPRDeviceClass. Except, that it
forgot to actually remove them from the VIOsPAPRBus structure (which
still exists, though it doesn't fulfill quite the same function as it
did pre-QOM).
This patch removes those now unused callback fields.

The "ICP" is a different object than the "XICS". For historical reasons,
we have a number of places where we name a variable "icp" while it contains
a XICSState pointer. There *is* an ICPState structure too so this makes
the code really confusing.
This is a mechanical replacement of all those instances to use the name
"xics" instead. There should be no functional change.

Reserve this to CPU state serialization.
Luckily, they were only used by sPAPR devices and these are ppc64
only. So there is no change to migration format.

The code for -machine pseries maintains a global sPAPREnvironment structure
which keeps track of general state information about the guest platform.
This predates the existence of the MachineState structure, but performs
basically the same function.
Now that we have the generic MachineState, fold sPAPREnvironment into
sPAPRMachineState, the pseries specific subclass of MachineState.
This is mostly a matter of search and replace, although a few places which
relied on the global spapr variable are changed to find the structure via
qdev_get_machine().

Instead of tweaking a TCE table device by adding there a bypass flag,
let's add an alias to RAM and IOMMU memory region, and enable/disable
those according to the selected bypass mode.
This way IOMMU memory region can have size of the actual window rather
than ram_size which is essential for upcoming DDW support.
This moves bypass logic to VIO layer and keeps @bypass flag in TCE table
for migration compatibility only. This replaces spapr_tce_set_bypass()
calls with explicit assignment to avoid confusion as the function could
do something more that just syncing the @bypass flag.
This adds a pointer to VIO device into the sPAPRTCETable struct to provide
the sPAPRTCETable device a way to update bypass mode for the VIO device.

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.

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
the DMAContext, or because dma_context_memory's AddressSpace is
trivially address_space_memory).

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
to retrieve the DMAContext from it.

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.
