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).

Is appears that the flag -
DCORE0_TPC0_CFG_STATUS_VECTOR_PIPE_EMPTY_MASK, has no actual use when
it comes to querying TPC idleness, since this flag's corresponding bit
turns-off after stalling the engine, and turns back on after resuming
it.

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.
