Merge tag 'drm-habanalabs-next-2023-04-10' of https://git.kernel.org/pub/scm/linux/kernel/git/ogabbay/linux into drm-next

This tag contains additional habanalabs driver changes for v6.4:

- uAPI changes:
  - Add a definition of a new Gaudi2 server type. This is used by userspace
    to know what is the connectivity between the accelerators inside the
    server

- New features and improvements:
  - speedup h/w queues test in Gaudi2 to reduce device initialization times.

- Firmware related fixes:
  - Fixes to the handshake protocol during f/w initialization.
  - Sync f/w events interrupt in hard reset to avoid warning message.
  - Improvements to extraction of the firmware version.

- Misc bug fixes and code cleanups. Notable fixes are:
  - Multiple fixes for interrupt handling in Gaudi2.
  - Unmap mapped memory in case TLB invalidation fails.

HW queues testing at driver load and after reset takes a substantial

Receiving events from FW, while the device is in hard reset, causes
a warning message in Driver log. The message may point to a
problem in the Driver or FW. But It also can appear as a result
of events that have been sent from FW just before the hard reset.
In order to avoid receiving events from FW while the device is in reset
and is already in 'disabled' mode, sync the f/w events interrupt right
before setting the device to 'disabled'.
