    bcm53xx: add support for ASUS RT-AC3100
    
    ASUS RT-AC3100 is ASUS RT-AC88U without the external switch.
    
    OpenWrt forum users effortless and ktmakwana have confirmed that there are
    revisions with either 4366b1 or 4366c0 wireless chips.
    
    Therefore, include firmware for 4366b1 along with 4366c0. This way, all
    hardware revisions of the router will be supported by having brcmfmac use
    the firmware file for the wireless chip it detects.
