    bcm27xx: add AMP2 to HifiBerry DAC+ / DAC+ Pro package
    
    According to the vendor [1] these HATs share the same DT overlay:
    hifiberry-dacplus. The PCM512x-compatible control unit is attached to
    I2C, so the additional snd-soc-pcm512x-i2c kernel module is required.
    Also explicitly note the Amp2 support to reduce confusion for those
    users.
