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.
