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] 
Code and DSDT exploration.
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.
