ACPICA: Update for "orphan" embedded controller _REG method support

Browse source

This refers to _REG methods under the EC device that have no
corresponding operation region. This is allowed by the ACPI
specification. This update removes a dependency on having an
ECDT table, and will execute an orphan _REG method as long as
the handler for the EC is installed at the EC device node (not
the namespace root).  Rui Zhang (original update), Bob Moore
(update/integrate).
