    packages: nvram: add set_bcm43602_variables quirk for ASUS RT-AC3200
    
    Broadcom BCM43602 needs certain NVRAM variables to be set to function. Add
    a quirk for it and add ASUS RT-AC3200 which has got Broadcom BCM43602 to
    the quirk. Thanks to Tom Brautaset for finding the needed variables.
