[PATCH net-next 08/13] net: dsa: lantiq_gswip: Consistently use macros for the mac bridge table

From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

Introduce a new GSWIP_TABLE_MAC_BRIDGE_PORT macro and use it throughout
the driver. Also update GSWIP_TABLE_MAC_BRIDGE_STATIC to use the BIT()
macro. This makes the driver code easier to understand.
