* Updated ACPICA to 20110623.

Browse Source 
See http://www.acpica.org/download/changes.txt done after 2010-10-13 for info on ACPI changes.
 * Adapted the embedded controller to match current FreeBSD one.

There will probably be some issues with these changes initially.

*
* As of 10/2010, the _PRW method execution has been removed since it is
