gpu: nvgpu: move channel_sync_gk20a.* to common directory

1) Move channel_sync_gk20a.* from gk20a/ to common/ directory as they
donot program any hardware registers. Also as an add-on rename
channel_sync_gk20a.* to channel_sync.* and update the headers
in required files.
2) Rename the struct gk20a_channel_sync to struct nvgpu_channel_sync. Also,
corresponding syncpt and semaphore versions of the struct alongwith
related methods are renamed by removing "gk20a" from their names and
adding "nvgpu".
3) Add misra-c cleanups
