Add nvgpu_* wrappers for determining if we're running in simulation

The new wrappers require struct gk20a pointer, and gk20a_fence_wait()

In preparation for better abstraction in job synchronization, drop
support for the dependency fences tracked via submit pre-fences in
semaphore-based syncs. This has only worked for semaphores, not nvhost
syncpoints, and hasn't really been used. The dependency was printed in
the sync framework's sync pt value string.
Remove also the userspace-visible gk20a_sync_pt_info which is not used
and depends on this feature (providing a duration since the dependency
fence's timestamp).

In gk20a_pm_shutdown(), we do not check return value
of gk20a_pm_prepare_poweroff
In some cases it is possible that gk20a_pm_prepare_poweroff()
returns -EBUSY (this could happen if engines are busy)
so we don't clean up s/w state and directly
trigger GPU railgate
In case some interrupt is triggered simultaneously
we try to access a register while GPU is already railgated
This leads to a hard hang in nvgpu shutdown path
Make below changes in shutdown sequence to fix this:
- check return value of gk20a_wait_for_idle()
- disable activity on all engines with
gk20a_fifo_disable_all_engine_activity()
- ensure engines are idle with gk20a_fifo_wait_engine_idle()
- check return value of gk20a_pm_prepare_poweroff()
- check return value of gk20a_pm_railgate()
Add a print when we bail out early in case
GPU is already railgated
Move to use new nvgpu_info/err() log messages
instead of dev_*() messages
