[Bagas Sanjaya]

kernel test robot reported htmldocs warning:

Documentation/iio/bno055.rst:2: WARNING: Explicit markup ends without a blank line; unexpected unindent.

The warning above is caused by missing blank line separator between SPDX
identifier and page title.

Add the blank line to fix the warning.
