[RFC 01/13] ACPI/IORT: Move IORT to the ACPI folder

IORT can be used (by QEMU) to describe a virtual topology containing an
architecture-agnostic paravirtualized device.

In order to build IORT for x86 systems, the driver has to be moved outside
of arm64/. Since there is nothing specific to arm64 in the driver, it
simply requires moving Makefile and Kconfig entries.
