Implement jailhouse_paravirt() via device tree probing on architectures
!= x86. Will be used by the PCI core.

Basic x86 support [1] for running Linux as secondary Jailhouse [2] guest
is currently pending in the tip tree. This builds on top and enhances
the PCI support for x86 and also ARM guests (ARM[64] does not require
platform patches and works already).
Key elements of this series are:
- detection of

Use the PCI mmconfig base address exported by jailhouse in boot
parameters in order to access the memory mapped PCI configuration space.

Not sure if those two worked by design or just by chance so far. In any
case, it's at least cleaner and clearer to express this in a single
config statement.

Per PCIe r4.0, sec 7.5.1.1.9, multi-function devices are required to
have a function 0. Therefore, Linux scans for devices at function 0
(devfn 0/8/16/...) and only scans for other functions if function 0
has its Multi-Function Device bit set or ARI or SR-IOV indicate
there are

Jailhouse does not use ACPI, but it does support MMCONFIG. Make sure the
latter can be built without having to enable ACPI as well. Primarily, we
need to make the AMD mmconf-fam10h_64 depend upon MMCONFIG and ACPI,
instead of just the former.
Saves some bytes in the Jailhouse no
