This change adds support to validate the hw_fence driver
by adding IOCTLs that expose the hw_fence interfaces so that
validation clients can register/unregister, create/destroy
and wait/signal fences. IOCTL's will be available for debug
purpose only when the debugfs config is set.

This change adds support for the hw-fence driver that initialize, expose
and manage the interfaces for the hw-fences, which are the synchronization
primitives to allow the hardware to hardware signalization of the fences
for the frame buffers shared between gpu and display hw-cores.
