staging: vt6655: Convert macro vt6655_mac_clear_stck_ds to function
Convert once used macro to static function. Multiline macros are not
liked by kernel community. Rename variable byOrgValue to reg_value to
avoid CamelCase which is not accepted by checkpatch.pl. Change variable
declaration to u8 as this improves readability.
