Subject: net: dsa: lantiq_gswip: Consistently use macros for the mac bridge
table
Only bits [5:0] in mac_bridge.key[3] are reserved for the FID.
Also, for dynamic (learned) entries, bits [7:4] in mac_bridge.val[0]
represents the port.
Introduce new macros GSWIP_TABLE_MAC_BRIDGE_KEY3_FID and
GSWIP_TABLE_MAC_BRIDGE_VAL0_PORT macro and use it throughout the driver.
Also rename and update GSWIP_TABLE_MAC_BRIDGE_VAL1_STATIC to use the
BIT() macro. This makes the driver code easier to understand.
