- Xavier has different SKUs based on which different engines are enabled
or disabled based on fuse setttings.
- This patch probes engines only if they are actually enabled in SKU by
reading SKU INFO.
- This makes sure that we dont access engines if they are enabled
inadvertently in DT

- Update TODO's
A. FW_VERSION was added for backward compatibility for legacy firmware.
As firmware ver <0.6.0 is expected not to be used in future, so remove
checks, macro and TODO comment it.
B. MAX_GRID_SIZE is not expected to managed through nvhost as that
indirectly managed in nvmap, so remove TODO comment.
C. Adding runtime checks in timeout for abort handler would add
few cycles.
- Send gos region if it fails in second attempt
A. GoS region fetch may fail for first poweron during device boot
GoS region may not be invoked/fail in second attempt
Explicitly attempt again if it failed in previous attempts
B. Mark invalid error for max num grids
C. Add more comments for future changes for GoS handling

registeres with host.
- GoS table required to send to falcon with
every poweron.
- Currently, GoS id fetched during task submit
data fill and before actual task submit.
- Engine is powered on just before task submit
- considering all these, it is necessary to fetch
GoS table before first task submit fill.

nvdla driver implemented a legacy PD implementation via
nvhost_domain_init(). There is a proper generic power domain provider
implementation for Tegra186 and later so this is unnecessary. Hence
remove all reference to it. While at it convert the module
initialization to use module_platform_driver() macro.

- Postfences should be ready for user before response from engine.
- this helps to avoid race between task complete, response to user and
user waiting on fence.
- So update postfence prior to register notifier and command submission.
- minimize engine poweron window by moving poweron call just before submit.
this should help to get better power number.

Emulator tasks execute on CCPLEX in DLA UMD thread but
these tasks need synchronization between other tasks
runing on DLA engine or some other engines.
Synchronization between DLA and other engines is through
sync point as NvMedia layer does not support semaphore.
This requires assigning and incrementing sync point
value for emulator tasks too.
This change adds an IOCTL to increment sync point
max value and report it back to UMD so that DLA UMD
can communicate it to other engines.

CV cluster clamping is currently owned partly by nvhost and partly by the
client modules in their poweroff sequences. This leads to a mismatch in
ref counts if the client specific finalize_poweron() call doesn't work.
nvhost side ends up retrying to boot the device three times at which point
we are left with a mismatch in the cluster clamp ref counts.
To fix this, move out cluster clamping back to nvhost which allows us to
maintain consistent state for the ref count.
