gpu: nvgpu: Enable -Wmissing-prototypes

Browse Source 
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.
