    ath79: Upstream b53 DSA driver for Ubiquiti EdgeSwitch 8XP
    
    The swconfig-based b53 driver for the BCM53128 switch stopped working
    after commits b2cfed48f6 (Revert "swconfig: fix Broadcom b53 support")
    and e4e410733f (kernel: export switch_generic_set_link() symbol). This
    rendered the 8 LAN ports of the EdgeSwitch 8XP non-functional, so the
    image compilation for the device was disabled (5a1d7d8c1b).
    
    This commit adds the kmod-dsa-b53-mdio and kmod-dsa-b53 packages
    with the upstream B53 DSA driver, replacing the swconfig-based
    kmod and kmod-switch-bcm53xx-mdio downstream ones that are not used by
    any other device.
    
    The 8 LAN ports of the EdgeSwitch 8XP are usable again. The 02_network
    init script has been updated with the new DSA interfaces lan1 .. lan8.
    
    Image building has been reenabled for the device, adding the usual DSA
    incompatibility notice.
    
    Tested on a Ubiquiti EdgeSwitch 8XP.
