habanalabs/gaudi2: add gaudi2 profiler module

Add the Gaudi2 code to initialize the ASIC's profiler. The profile
receives its initialization values from the user, same as in Gaudi2,
but the code to initialize is in the driver because the configuration
space of the device is not directly exposed to the user.
