[PATCH v3 2/9] xen/asm-generic: Introduce generic acpi.h

[Shawn Anastasio <sanastasio@raptorengineering.com>]

Introduce a generic acpi.h header that provides the required definitions
to allow files including xen/acpi.h to be compiled. The definitions were
largely derived from the !CONFIG_ACPI parts of ARM's acpi.h.
