net: dsa: b53: Prepare to support 7445 switch

Allocate a device entry for the Broadcom BCM7445 integrated switch currently backed by bcm_sf2.c. Since this is the latest generation, it has 4 ARL entries, 4K VLANs and uses Port 8 for the CPU/IMP port. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
