This tag contains habanalabs driver changes for v6.8.

- uAPI changes:
- Add sysfs entry to allow users to identify a device minor id with its
debugfs path
- Add sysfs entry to expose the device's module id as given to us from
the f/w
- Add signed device information retrieval through the INFO ioctl
- New features and improvements:
- Update documentation of debugfs paths
- Add support for Gaudi2C device (new PCI revision number)
- Add pcie reset prepare/done hooks
- Firmware related fixes and changes:
- Print three instances version numbers of Infineon second stage
- Assume hard-reset is done by f/w upon PCIe AXI drain
- Bug fixes and code cleanups:
- Fix information leak in sec_attest_info()
- Avoid overriding existing undefined opcode data in Gaudi2
- Multiple Queue Manager (QMAN) fixes for Gaudi2
- Set hard reset flag if graceful reset is skipped
- Remove 'get temperature' debug print
- Fix the new Event Queue heartbeat mechanism
