  habanalabs: add more protection of device during reset (2019-11-21 11:35:47 +0200)

----------------------------------------------------------------
This tag contains the following changes for kernel 5.5:

- MMU code improvements that includes:
  - Distinguish between "normal" unmapping and unmapping that is done as
    part of the tear-down of a user process. This improves performance of
    unmapping during reset of the device.
  - Add future ASIC support in generic MMU code.

- Improve device reset code by adding more protection around accessing the
  device during the reset process.

- Add new H/W queue type for future ASIC support

- Add more information to be retrieved by users through INFO IOCTL:
  - clock rate
  - board name
  - reset counters

- Small bug fixes and minor improvements to code.
