This experimental patch series allows WMI drivers to retrieve
the number of WMI object instances. This functionallity benefits
several current and upcoming WMI drivers, the dell-wmi-sysman driver
is converted to use this new API as an example.

The changes are compile-tested only, the change to the dell-wmi-sysman
driver also needs to be tested on real hardware.
