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.

SW Profiler's debugfs entry "enable" has both RW permissions set
however the corresponding read operation is set to NULL.
Similarly, the other entries i.e. "percentiles", "raw_entries" and
"basic_stats" only have a read operation defined and write is set to
NULL.
To enable correct permissions, set permission for "enable" to "W"
and set permissions for others as "R" only.

GVS: Gerrit_Virtual_Submit
The current debugfs code is completely specific to FIFO's kickoff
profiler. But exposing these debugfs nodes is really a perfectly
generic operation to any given profiler.
Therefore add a generic debugfs interface for exposing profilers.
Any code that implements a profiler can now use a single function
call to export a profiler to the GPU debugfs area.
