docs: Added exclude to Doxyfile for boschdriver src.

The boschdriver.h file contains tags which are picked up by
doxygen and cause incorrect results.  For example, the
\mainpage and \license cause the Bosch header collateral to
be placed on the index.html page of the UPM docs.

Added an entry to EXCLUDE_PATTERNS which handles this.
