habanalabs: add gaudi2 asic-specific code

Add the ASIC-specific code for Gaudi2. Supply (almost) all of the
function callbacks that the driver's common code need to initialize,
finalize and submit workloads to the Gaudi2 ASIC.

It also contains the code to initialize the F/W of the Gaudi2 ASIC
and to receive events from the F/W.

It contains new debugfs entry to dump razwi events. razwi is a case
where the device's engines create a transaction that reaches an
invalid destination.
