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.
