  core: ivshmem: Introduce separate header file

Stop piggybacking with PCI for ivshmem-specific prototypes. This will
help making non-x86 support for ivshmem cleaner.

We already move the struct pci_ivshmem_endpoint into the header because
the arch-specific code will need it.

  core: ivshmem: Remove "pci" tagging from function and module names

The ivshmem device is PCI-only, and it seems it will remain like that,
even when expanding to targets without physical PCI support. Therefore,
it adds no value to have "pci_" in its names all over the place because
the will be no PCI-free variant in parallel.

Besides the renaming, this also consolidates pci_ivshmem_update_msix and
ivshmem_update_msix into a single service.

  arm, arm64: Prepare for PCI support

This adds the required stubs and functions of physical PCI support on
ARM and ARM64. It also switches to building the generic PCI and ivshmem
modules unconditionally for all archs. Mapping the MMCONFIG space will
require a larger remapping region, so this is extended on both ARM and
ARM64.

This does not yet initialize PCI for the new archs, though. Moreover,
ivshmem interrupt delivery is not yet implemented.

GICD-based injection being requested if a NULL target CPU is passed.

  arm-common: Add MSI-X support for ivshmem devices based on GICv2m

If system comes with a GICv2m, we can piggyback with it to emulate MSI-X
vector support of ivshmem. GICv2m means that the MSI data field contains
the target interrupt number, to be injected into the GICD. We validate
and cache the value on arch_ivshmem_update_msix and simply inject it via
the physical GICD on arch_ivshmem_write_doorbell.

Yet missing is validation of the MSI address field. Also, we do not have
any of the GICv2m quirk workaround implemented that Linux carries
because our reference system, AMD Seattle, is implemented according to
the Server Base System Architecture spec.

  driver: Register virtual PCI controller via device tree overlay

In order to add a virtual PCI host controller to the root cell after
Jailhouse activation on ARM/ARM64, we need to inject a device tree
modification. For this purpose, overlays were invented and are already
support by upstream since 3.19.

All we need to do is to fill a fragment template with some variable
parameters that can be derived from the system configuration: virtual
IRQ base, ECAM base address, and the uncached memory window size, which
can be derived from the number of ivshmem devices. We also need to
resolve the link to the GIC as the host's device tree may not have the
required symbols included.

Once the fragment is patched, we can register it, and Linux will detect
and handle the new platform device.

Note that the upstream pci-host-generic Linux driver still has issues
when it comes to unloading (and actually also rollback on errors).
Fixing this is WiP.

To use this feature with the Tegra K1, the kernel has to be patched to
allow multi-domain PCI so that a second PCI host controller can be
enabled besides the non-extensible physical controller (see
https://groups.google.com/d/msg/jailhouse-dev/5BnCAFAzykI/wHgj2UUbCwAJ).
