[ACPI] better fix for pnpacpi regression resulting from ACPICA 20051117

Rather than tweaking acpi_walk_resource() again not return end tags,
modify the pnpacpi code to ignore them.

The pnpacpi resource type switch statements now include all known
types in the order that they're defined -- so it is easy to see
what is not implemented.  The code will squawk only if it sees
a truly undefined type.
