[PATCH 3/3] ARM: DTS: omap5-uevm: Enable basic audio (McPDM <-> twl6040)

The board uses twl6040 codec connected via McPDM link. McBSP1 and McBSP2 can
be used for FM/BT.
At the same time move the pinctrl handling to the correct place - under the
corresponding nodes.
Audio connectors on the board:
Headset in/out
Stereo Line out
Stereo Line in.
