ARM: dts: imx6ul-14x14-evk: Add audio support
imx6ul-14x14-evk has a wm8960 codec connected via SAI2 port. Add support for it. Thanks to Petr Kulhavy <brain@jikos.cz> for the hint on initializing the PLL4 frequency to get a correct MCLK. Signed-off-by: Fabio Estevam <fabio.estevam@nxp.com> Signed-off-by: Shawn Guo <shawnguo@kernel.org>
