Allow SC7 suspend/resume for platforms even if runtime pm
is disabled.
Currently, nvgpu can disable runtime pm by setting railgate_init
field to false for platform_{gk20a/gv11b/ga10b) files. This is done by
taking extra reference count in the PM Framework.
However, device suspend would still fail. Fix this by checking
for NVGPU_CAN_RAILGATE and removing the additional reference count
taken as mentioned above. Take the extra refcount back at
the end of the resume path.

Create device nodes for user-created scheduling domains. This helps
leverage filesystem based access control: domains can be chosen to be
available for a limited set of users on a system.
The device nodes are dynamic: they can be removed while the driver is
running normally. This is a bit different from the nodes that exist
until the driver is unloaded, so the devno/domain mapping is stored in a
separate list. The usual container_of pattern would suffer from an
unavoidable race condition if a domain file was opened while the same
domain would get removed.
As usual, domain refcounting prevents a domain from being removed. Now
the open device files hold refs and thus any open domain files prevent a
domain from getting removed, in addition to the userspace-invisible ref
that is taken when a TSG is bound to a domain.
While at it, make the query ioctl guarded by the sched domain mutex, as
domains might technically get added or removed during the querying code.

- Removes the reporting of error messages.
- Replaces nvgpu_log() with nvgpu_err(), for error reporting.
- Removes error reporting to Safety_Services from nvgpu_report_*_err.

Note:
- There will be a follow-up patch to fix error IDs.

The nvgpu timeout API has an internal override for presilicon mode by
default: in presi simulation environments the timeouts never trigger.
This behaviour is intended in the original usecase of the timer unit
with hardware polling loops. In pure software logic though, the timer
must trigger after the specified timeout even in presi mode so add a new
init function to produce a timer for software logic. Use this new kind
of timer in channel and scheduling worker threads.
The channel worker currently times out for just the purpose of the
channel watchdog timer which has its own internal timer. Although that's
just software, the general expectation is that the watchdog does not
trigger in presilicon tests that run slower than usual. The internal
watchdog timer thus keeps the non-sw mode.

1) It avoids an infinite loop when collecting VAB information.
Previously, nvgpu incorrectly assumed that the valid bit would

if a VAB-related fault has occurred.
2) It handles the VAB_ERROR mmu fault which may be caused for various
reasons: invalid vab buffer address, tracking in protected mode,
etc. The recovery sequence is to set the vab buffer size to 0 and
then to the original size. This clears the VAB_ERROR bit. After
reseting, the old register values are again set in the recovery
code sequence.
3) Use correct number of VAB buffers. There's only one VAB buffer on
