platform/x86: wmi: Instantiate all devices before adding them

At some point, we will want sub-drivers to get references to other

This is based on the original work of Andy Lutomirski <[email protected]>,
but includes several modifications, many in response to review from
Michał Kępień <[email protected]>:
