- Add Gaudi2 ASIC support. All the features required for Gaudi2 are included
in this tag (except the networking aspect).
- Add more events to the eventfd support in the driver. With the new code, we
expose three events that the user can register to get notification about them.
- re-factor soft reset code and replace its name to compute reset to better
reflect the actual reset done in new ASICs
- Change the way Gaudi2 triggers an MSI-X interrupt due to h/w bug.
- Improve the code of the debugfs node that scrubs the device's memory.
- Add mechanism for better compatibility with older f/w versions
- Cleanup kernel log prints by moving some prints to debug and removing others.
- Many small bug fixes and minor changes.
