Subject: [PATCH v2 5/6] staging: vt6655: Convert macro
 MACvEnableBarkerPreambleMd

Convert macro MACvEnableBarkerPreambleMd to static function which calls
the common static function vt6655_mac_set_bits. This saves
codelines and multiline macros are not liked by kernel community.
Function name is also changed to avoid CamelCase which is not accepted
by checkpatch.pl and to clean up namespace.
