261d4bed13 gpu: nvgpu: Enable -Wmissing-prototypes 
The compiler option -Wmissing-prototypes is being enabled globally in
the upstream Linux kernel and this causes build failures for nvgpu. The
build failures occur because either the driver is missing an include
file which has the prototype or because the function is not declared
statically when it should be (ie. there are no external users).

Fix the various build failures and enable -Wmissing-prototypes to
prevent any new instances from occurring.

23d6b36101 gpu: nvgpu: add dma_fence semaphore support 
Support exporting and importing semaphore-based synchronization with the
stable dma-fence API. The "Android" sync fence API used until now is
deprecated.

The Android sync framework is still kept as the default.
