Subject: [PATCH 09/13] ARM: dts: mmp2-olpc-xo-1-75: Enable audio support

This enables the audio SRAM, DMA engine, I2S interface, and codec, hooks
them together and adds a audio-graph-card instance.

It also removes the jack gpios from the gpio-keys instance, because the
audio jack driver registers an input device.
