[ Upstream commit 4d26e9a028e3d88223e06fa133c3d55af7ddbceb ]
Older versions of U-Boot would pinmux the whole board, but as the bootloader got updated, it started to only pinmux the pins it needed, and expected Linux to configure what it needed.
Unfortunately this caused an issue with the audio, because the mcbsp2 pins were configured in the device tree but 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.
Fixes: 5cb8b0fa55a9 ("ARM: dts: Move most of logicpd-som-lv-37xx-devkit.dts to logicpd-som-lv-baseboard.dtsi")
