This patch refines the ACPI device passthrough framework by defining a
generic framework. Note that when user gives an HID by "--acpidev_pt
<HID>", the pt logic will go through all registered ops to see if
there's a match.
v4 -> v5:
parse_pt_acpidev/parse_pt_mmiodev -> create_pt_acpidev/create_pt_mmiodev
(there were already "init_xxx" function present, so rename to
create_xxx)
"super user" -> "superuser"
multiple API renames
