mlxsw: spectrum: Add bridge dependency for spectrum

When BRIDGE is a loadable module, MLXSW_SPECTRUM mustn't be built-in:

drivers/built-in.o: In function `mlxsw_sp_bridge_device_create':
drivers/net/ethernet/mellanox/mlxsw/spectrum_switchdev.c:145: undefined reference to `br_vlan_enabled'
drivers/net/ethernet/mellanox/mlxsw/spectrum_switchdev.c:158: undefined reference to `br_multicast_enabled'
drivers/built-in.o: In function `mlxsw_sp_dev_rif_type':
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:2972: undefined reference to `br_vlan_enabled'
drivers/built-in.o: In function `mlxsw_sp_inetaddr_vlan_event':
drivers/net/ethernet/mellanox/mlxsw/spectrum_router.c:3310: undefined reference to `br_vlan_enabled'

Add Kconfig dependency to enforce usable configurations.
