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

Convert macro MACvDisableBarkerPreambleMd to static function which calls
the common static function vt6655_mac_clear_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.

V1 -> V2: Changed used function to vt6655_mac_clear_bits
