To support Hyper-V Dom0 (aka Linux as root partition), many new
definitions are required.

The plan going forward is to directly import definitions from
Hyper-V code without waiting for them to land in the TLFS document.
This is a quicker and more maintainable way to import definitions,
and is a step toward the eventual goal of exporting headers directly
from Hyper-V for use in Linux.

This patch series introduces new headers (hvhdk.h, hvgdk.h, etc,
see patch #3) derived directly from Hyper-V code. hyperv-tlfs.h is
replaced with hvhdk.h (which includes the other new headers)
everywhere.

No functional change is expected.

Summary:
Patch 1-2: Minor cleanup patches
Patch 3: Add the new headers (hvhdk.h, etc..) in include/hyperv/
Patch 4: Switch to the new headers

Changelog:
v2:
- Rework the series to simply use the new headers everywhere
  instead of fiddling around to keep hyperv-tlfs.h used in some
  places, suggested by Michael Kelley and Easwar Hariharan
- Fix compilation errors with some configs by adding missing
  definitions and changing some names, thanks to Simon Horman for
  catching those
- Add additional definitions to the new headers to support them now
  replacing hyperv-tlfs.h everywhere
- Add additional context in the commit messages for patches #3 and #4
- In patch #2, don't remove indirect includes. Only remove includes
  which truly aren't used, suggested by Michael Kelley
