ACPICA: Execute an orphan _REG method under the EC device

Browse Source 
This change will force the execution of a _REG method underneath
the EC device even if there is no corresponding operation region
of type EmbeddedControl. Fixes a problem seen on some machines
and apparently is compatible with Windows behavior.
