This commit adds the necessary Device Tree informations to enable audio support on the Armada 370 DB platform. In details it: * Instantiates the CS42L51 audio codec on the I2C0 bus, and configures this bus with the appropriate pin-muxing configuration. * Enables the I2S audio controller, and configures it with the appropriate pin-muxing configuration. * Through hog pins, ensures that the other pins possibly used for I2S are muxed with another function than I2S.
