6092cedfff accel/habanalabs: print qman data on error only for lower qman
By default, the upper QMANs are not used, and instead engines ARCs
access the lower QMANs directly.
Errors for upper QMANs are therefore not expected, and the debug print
of the PQ entries is not needed.

Modify the QMAN debug data print on errors to include only information
for the lower QMAN.

91204e4703 accel/habanalabs: fix handling of arc farm sei event
There is only single eq entry for arc farm sei event which aggregates
events from the four arc farms.
Fix the code to handle this event according to this behavior.

f7f0085eec accel/habanalabs: add uapi to stall/resume engine
The user might want to stall/resume engines to perform power testing
for various scenarios. Because our current
HL_CS_FLAGS_ENGINE_CORE_COMMAND command only handles the engines' cores,
we need to add another opcode for handling entire engine and not just
its core.

The user supplies an array, where each entry holds the engine's ID and
the command to send to the engine. The size of the array is limited
by the number of engines in the ASIC (only Gaudi2 is currently
supported).

6cfb00139d habanalabs/gaudi2: avoid reconfiguring the same PB registers
It appears that, within the sync manager security configuration,
we reconfigure PB registers over and over without any need to do that.

e65e175b07 habanalabs: move driver to accel subsystem
Now that we have a subsystem for compute accelerators, move the
habanalabs driver to it.

This patch only moves the files and fixes the Makefiles. Future
patches will change the existing code to register to the accel
subsystem and expose the accel device char files instead of the
habanalabs device char files.

Update the MAINTAINERS file to reflect this change.
