Get rid of all the gunk and remove the 'select PCI_MSI_ARCH_FALLBACK' from
the x86 Kconfig so the weak functions in the PCI core are replaced by stubs
which emit a warning, which ensures that any fail to set the irq domain
pointer results in a warning when the device is used.

The arch_.*_msi_irq[s] fallbacks are compiled in whether an architecture
requires them or not. Architectures which are fully utilizing hierarchical
irq domains should never call into that code.
It's not only architectures which depend on that by implementing one or
more of the weak functions, there is also a bunch of drivers which relies
on the weak functions which invoke msi_controller::setup_irq[s] and
msi_controller::teardown_irq.
Make the architectures and drivers which rely on them select them in Kconfig
and if not selected replace them by stub functions which emit a warning and
fail the PCI/MSI interrupt allocation.

Now that interrupt remapping sets the irqdomain pointer when a PCI device
is added it's possible to store the default irq domain in the device struct
in pcibios_add_device().
If the bus to which a device is connected has an irq domain associated then
this domain is used otherwise the default domain (PCI/MSI native or XEN
PCI/MSI) is used. Using the bus domain ensures that special MSI bus domains
like VMD work.
This makes XEN and the non-remapped native case work solely based on the
irq domain pointer in struct device for PCI/MSI and allows to remove the
arch fallback and make most of the x86_msi ops private to XEN in the next
steps.

To support MSI irq domains which do not fit at all into the regular MSI
irqdomain scheme, like the XEN MSI interrupt management for PV/HVM/DOM0,
it's necessary to allow to override the alloc/free implementation.
This is a preperatory step to switch X86 away from arch_*_msi_irqs() and
store the irq domain pointer right in struct device.
No functional change for existing MSI irq domain users.
Aside of the evil XEN wrapper this is also useful for special MSI domains

Composing the MSI message at the MSI chip level is wrong because the

composed for the direct vector delivery or the interrupt remapping table
entry.
The interrupt remapping aware PCI/MSI chip does that already. Make the

The documentation of irq_chip_compose_msi_msg() claims that with
hierarchical irq domains the first chip in the hierarchy which has an
irq_compose_msi_msg() callback is chosen. But the code just keeps
iterating after it finds a chip with a compose callback.
The x86 HPET MSI implementation relies on that behaviour, but that does not
make it more correct.
The message should always be composed at the domain which manages the
underlying resource (e.g. APIC or remap table) because that domain knows
about the required layout of the message.
On X86 the following hierarchies exist:
1) vector -------- PCI/MSI
2) vector -- IR -- PCI/MSI
The vector domain has a different message format than the IR (remapping)
domain. So obviously the PCI/MSI domain can't compose the message without
having knowledge about the parent domain, which is exactly the opposite of
what hierarchical domains want to achieve.
X86 actually has two different PCI/MSI chips where #1 has a compose
callback and #2 does not. #2 delegates the composition to the remap domain
where it belongs, but #1 does it at the PCI/MSI level.
For the upcoming device MSI support it's necessary to change this and just
let the first domain which can compose the message take care of it. That
way the top level chip does not have to worry about it and the device MSI
code does not need special knowledge about topologies. It just sets the
compose callback to NULL and lets the hierarchy pick the first chip which
has one.
Due to that the attempt to move the compose callback from the direct
delivery PCI/MSI domain to the vector domain made the system fail to boot
with interrupt remapping enabled because in the remapping case
irq_chip_compose_msi_msg() keeps iterating and choses the compose callback
of the vector domain which obviously creates the wrong format for the remap
table.
Break out of the loop when the first irq chip with a compose callback is
found and fixup the HPET code temporarily. That workaround will be removed
once the direct delivery compose callback is moved to the place where it
belongs in the vector domain.

VMD has it's own PCI/MSI interrupt domain which is not in any way depending
on the x86 vector domain. PCI devices behind VMD share the VMD MSIX vector
entries via a VMD specific message translation to the actual VMD MSIX
vector. The VMD device interrupt handler for the VMD MSIX vectors invokes
all interrupt handlers of the devices which share a vector.
Making the x86 vector domain the actual parent of the VMD irq domain is
pointless and actually counterproductive. When a device interrupt is
requested then it will activate the interrupt which traverses down the
hierarchy and consumes an interrupt vector in the vector domain which is
never used.
The domain is self contained and has no parent dependencies, so just hand
in NULL for the parent and be done with it.
