    bcm27xx: bcm2711: add kmod-usb-net-lan78xx
    
    Some vendors like Seeedstudio in their product [1] with Raspberry Pi
    Compute Module 4 uses Microchip LAN7800 (USB 3.0 to Gigabit
    Ethernet Bridge) - USB 3.0 extended from PCIe of CM4.
    
    lsusb output:
    ```
    Bus 002 Device 002: ID 0424:7800 Microchip LAN7800
    ```
    
    Raspberry Pi 4 and even Compute Module 4 has many resources available
    and for just one kernel module it is not necessary to add additional specific CM4 profiles.
    Let's include it by default, so the both Ethernet ports will be usable
    to have better user-experience. Because previous generation of Raspberry
    Pi included LAN7800 Gigabit Ethernet by default and it is enabled there
    [2] in kernel without additional kernel module, which was added recently [3].
    
    After this commit in dmesg can be found this:
    
    ```
    root at OpenWrt:~# dmesg | grep lan
    [    7.038889] lan78xx 2-3:1.0 (unnamed net_device) (uninitialized): int urb period 64
    [    7.090484] usbcore: registered new interface driver lan78xx
    ```
    
    Tested and works with sysupgrade image.
