Changes in v6:
- Move the code to get the maintenance interrupt later. It will
avoid to call acpi_unregister_gsi when the function fails
The ACPI code requires to use global variables in order to collect
information from the tables.
For now, a single global variable is used, but more will be added in a
subsequent patch. To make clear they are ACPI specific, gather all the
information in a single structure.

They are not used in common code expect in one place in balloon.c which is
only compiled when Linux is using PV MMU. It's not the case on ARM.
Rather than worrying how to handle the 64KB case, drop them.
