staging: vt6655: Convert macro MACvSetBBType to function

Convert macro to static function. Multiline macros are not liked by
kernel community. Rename variable dwOrgValue to reg_value and byTyp to
mask to avoid CamelCase which is not accepted by checkpatch.pl. Change
variable declaration to u32 as this improves readability.
