    ath79: teltonika-rut230: drop reg_usb_vbus
    
    USB VBUS regulator was attached to GPIO19, which isn't in fact
    controlling the modem power itself, but rather modem power key - which
    has to be asserted high for at least 500ms, to start the modem. Keeping
    it high allows the modem to reboot upon shutdown - so it is desirable to
    control this line from userspace, for example - to allow clean modem
    shutdown down upon powering off the router part.
