ACPICA commit 4b86d1046d06e462dae83ebcd5a66cc132a08f8f

SuperName parameters that are in fact control method invocations were
not handled correctly by the parser. This change fixes the problem
by identifying these properly as method invocations. This affects
about 14 different ASL operators that contain SuperName parameters.
ACPICA BZ 1002.

ACPICA commit 918a840d27d620942e0ecb69de320bb71ea86c5a

ElseIf is a macro that resolves to an Else..If in the AML byte code.
This support merges an Else followed immediately by an If to an
ASL ElseIf operator. Simplifies decoded ASL, especially for large
Switch statements.

This patch only applies to iasl, and is no-op for Linux kernel.

ACPICA commit 80e60d72959bb51c5d08c8500d978607a42ed81d

BIOS developers may accidently put the quotes around the name strings,
which converts the object references in the packages indicated by the name
strings into the data objects (strings). Such kind of error has been seen
in _DEP control methods on some platforms. This patch implements a
workaround to correct it. Reported by Bastien Nocera. Fixed by Lv Zheng.

This reverts commit 8e7a8753827660c3dd1f571f3185610402b756f0.

The _SUB method was found to be problematic for this interface
because some implementations use control methods. Therefore,
it is being removed.

Operations cannot be used because this interface is called
during the device discovery scan and the region handlers are
not fully installed at that time.
