    ARM: BCM53016: Specify switch ports for Meraki MR32
    
    [ Upstream commit 6abc4ca5a28070945e0d68cb4160b309bfbf4b8b ]
    
    the switch identifies itself as a BCM53012 (rev 5)...
    This patch has been tested & verified on OpenWrt's
    snapshot with Linux 5.10 (didn't test any older kernels).
    The MR32 is able to "talk to the network" as before with
    OpenWrt's SWITCHDEV b53 driver.
