    bcm53xx: add support for Asus RT-AC88U
    
    Asus RT-AC88U is an AC3100 router featuring 9 Ethernet ports over the
    integrated Broadcom and the external Realtek switch.
    
    Hardware info:
    * Processor: Broadcom BCM4709C0KFEBG dual-core @ 1.4 GHz
    * Switch: BCM53012 in BCM4709C0KFEBG & external RTL8365MB
    * DDR3 RAM: 512 MB
    * Flash: 128 MB (ESMT F59L1G81LA-25T)
    * 2.4GHz: BCM4366 4×4 2.4/5G single chip 802.11ac SoC
    * 5GHz: BCM4366 4×4 2.4/5G single chip 802.11ac SoC
    * Ports: 8 Ports, 1 WAN Ports
    
    Flashing instructions:
    * Boot to CFE Recovery Mode by holding the reset button while power-on.
    * Connect to the router with an ethernet cable.
    * Set IPv4 address of the computer to 192.168.1.2 subnet 255.255.255.0.
    * Head to http://192.168.1.1.
    * Reset NVRAM.
    * Upload the OpenWrt image.
    
    CFE bootloader may reject flashing the image due to image integrity check.
    In that case, follow the instructions below.
    
    * Rename the OpenWrt image as firmware.trx.
    * Run a TFTP server and make it serve the firmware.trx file.
    * Run the URL below on a browser or curl.
