Convert WMI to a proper bus

From: "Darren Hart (VMware)" <[email protected]>

This series is based on the original work of
Andy Lutomirski <[email protected]> [1]. I have made minor edits, and in one instance, squashed two patches in which the latter undid the former.

This series converts WMI [2] into a proper bus, adds some useful information via sysfs, and exposes the embedded MOF [3] binary. It converts dell-wmi to use the new WMI bus architecture.

This is the first part of an ongoing effort to enhance the WMI infrastructure within the kernel, and eventually expose WMI to userspace for the consumption of management utilities as it was intended.
