The audio codec on Snow board, MAX98095 is connected on I2C7 bus.
Also it requires the GPX1-7 line to be pulled up.
Updated Snow DTS file to incorporate above changes and added a
sound node to instantiate the I2S-based sound card.

The audio setup on Peach-pit board is similar to Snow board, hence the
sound-card driver used on Snow board can be reused on Peach-pit board.
Peach-pit board uses MAX98090 audio codec.
