Gather all VFIORegion related declarations and definitions into their
own files to reduce exposure of VFIO internals in "hw/vfio/vfio-common.h".
They were introduced for 'vfio-platform' support in commits
db0da029a1 ("vfio: Generalize region support") and a664477db8
("hw/vfio/pci: Introduce VFIORegion").
To be noted that the 'vfio-platform' devices have been deprecated and
will be removed in QEMU 10.2. Until then, make the declarations
available externally for 'sysbus-fdt.c'.

Headers in include/sysemu/ are not only related to system
*emulation*, they are also used by virtualization. Rename
as system/ which is clearer.
Files renamed manually then mechanical change using sed tool.

"platform" is not a valid name for a bus node in dt-schema, so warnings
can be see in dt-validate on a dump of the riscv virt dtb:
/stuff/qemu/qemu.dtb: platform@4000000: $nodename:0: 'platform@4000000' does not match '^([a-z][a-z0-9\\-]+-bus|bus|soc|axi|ahb|apb)(@[0-9a-f]+)?$'
From schema: /home/conor/.local/lib/python3.9/site-packages/dtschema/schemas/simple-bus.yaml
"platform-bus" is a valid name, so use that instead.

The ARM virt machine currently uses sysbus-fdt to create device tree
entries for dynamically created MMIO devices.
The RISC-V virt machine can also benefit from this, so move the code to
the core directory.
