habanalabs: add unsupported functions

Browse Source 
There are a number of new ASIC-specific functions that were added
for Gaudi2. To make the common code work, we need to define empty
implementations of those functions for Goya and Gaudi.

Some functions will return error if called with Goya/Gaudi.
