x86: Detect running on a Microsoft HyperV system
This patch integrates HyperV detection within the framework currently
used by VmWare. With this patch, we can avoid having to replicate the
HyperV detection code in each of the Microsoft HyperV drivers.
Reworked and tweaked by Greg K-H to build properly.
