accel/ivpu: Improve buffer object debug logs

accel/ivpu: Improve buffer object debug logs

Make debug logs more readable and consistent:
  - don't print handle as it is not always available for all buffers
  - use hashed ivpu_bo ptr as main buffer identifier
  - remove unused fields from ivpu_bo_print_info()
