accel/habanalabs/gaudi2: perform hard-reset upon PCIe AXI drain event

Non-completed transactions from PCIe towards the device are handled by
the AXI drain mechanism. This handling is in the PCIe level, but the
transactions are still there in the device consuming some queues
entries, and therefore the device must be reset.
Modify to perform hard-reset upon PCIe AXI drain events.

accel/habanalabs/gaudi2: handle eq health heartbeat check

Add mechanism for fw eq health check. this will be done using two flows:
using the heartbeat mechanism and raising a dedicated interrupt to
indicate an eq failure like EQ full.
This patch will add implementation for the eq heartbeat for gaudi2 asic.

More info about the heartbeat mechanism:
Expand the heartbeat mechanism to monitor a new event that
will be sent from FW upon receiving heartbeat message.
that way driver can know that the eq is working or not.

When getting an event, add the ability to deduce the reset type from
the IRQ map table instead of using hard reset regardless.

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.
