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.

There are a few events that can arrive from the f/w and without proper
handling can cause errors to appear in the kernel log without reason.
Add the relevant handling that was missing.

We add support for NIC DERR ECC error events, in case this error
is received a device reset will be performed.

Currently driver sends fc interrupt id to FW instead of using
cpu interrupt id. We intend to fix that and keep backward
compatibility by using the same interrupt values.

In order for driver to be aware of process or thread crashes inside
GAUDI's CPU, we introduce a new event which contains all relevant
information. Upon event reception, driver will dump information and
will reset the device.

In case the BMC of the devices' box wants to initiate a reset of
a specific device, it must go through driver.
Once driver will receive the request it will initiate a hard reset
flow.

As the F/wW is the first to detect out of sync event, a new event is
added to notify the driver on such event. In which case the driver
performs hard reset.

Add the relevant GAUDI ASIC registers header files. These files are
generated automatically from a tool maintained by the VLSI engineers.
There are more files which are not upstreamed because only very few defines
from those files are used in the driver. For those files, we copied the
relevant defines into gaudi_regs.h and gaudi_masks.h, to reduce the size of
this patch.
