gpu: nvgpu: move nvgpu_has_syncpoints

Browse Source 
nvgpu_has_syncpoints is more general than a channel synchronization
related, so move it to nvhost.c from channel_sync.c. Move the
declaration from gk20a.h to nvhost.h.

As the debugfs knob is Linux related, move it from struct gk20a to
struct nvgpu_os_linux.
