[PATCH 2/5] ARM: dts: omap2420-n810: Correct the audio codec (tlv320aic33) node

[Peter Ujfalusi <peter.ujfalusi@ti.com>]

The n810 uses tlv320aic33 codec.
GPIO118 is used as reset GPIO for the codec, which was missing.
The MCLK of the codec is connected to the SYS_CLKOUT2 of omap2420. The
SYS_CLKOUT2 needs to be running at 12MHz.

Add the pinctrl entries to configure the pins for GPIO118 and SYS_CLKOUT2.
