Unfortunately this caused an issue with the audio, because the mcbsp2 pins were configured in the device tree, they were never referenced by the driver. When U-Boot stopped muxing the audio pins, the audio died. This patch adds the references to the associate the pin controller with the mcbsp2 driver which makes audio operate again.
