    intel/strago: BCRD2: Enable Realtek Audio codec on I2C4
    
    In BCRD2, RTEK audio codec is connected to I2C4.
    Create a RTEK device entry on I2C4 to enable Audio
    on BCRD2. In BCRD1, RTEK device is connected to I2C2.
    Having two devices with same HID breaks the Audio
    on BCRD2 even if I2C2.RTEK._STA returns 0. The Audio
    codec driver in kernel is hard coded to use first
    instance of the device (:00). When two devices are present
    with same HID, first device gets an instance number :00
    even though _STA returns 0. Second device which is on I2C4
    and POR for BCRD2 assigned with instance number :01. The
    device with :01 is not getting enabled since the Audio codec
    driver supports only :00. This need a proper fix in kernel
    which is in the pipeline. Audio on non BCRD2 platforms on
    Strago build would be disabled since RTEK device is not present
    on I2C2.
