>Description:

The so-called WMI may contain EC's operation regions. These need to be
passed to acpiec(4) to ensure that we do not open a can of worms.
This may also cure some of the infamous ACPICA error messages such as:

	ACPI Error (evregion-0666): No handler for Region [FOOBAR]
	(ffffff0000000000) [EmbeddedControl] [20070126]

>How-To-Repeat:

Code and DSDT exploration.

>Fix:

The acpiwmi(4) driver should install EC address space handler and pass
everything to acpiec(4) by using acpiec_bus_read() and acpiec_bus_write().

Note that this is already done in the equivalent FreeBSD driver.
