If we reduce the suspend function for intel_opregion to do the minimum
required, the resume function can also do the simple task of notifier
the ACPI bios that we are back. This avoid some nasty restrictions on
the likes of register_acpi_notifier() that are not allowed during the
early phase of resume.
v2: Keep the order of acpi notify vs turning off ardy/drdy the same.

We already have dedicated file for opregion related code, dedicated
header will make our life easier.
v2: reorder includes (Chris)
