ASoC: sta350: Add codec driver
The TI STA350 is an integrated 2.1-channel power amplifier that is controllable over I2C. This patch adds an ASoC driver for it. At a glance, this chip is very similar to the STA320 for which a driver already exists. In details, however, the register maps contain subtle differences which made a whole new driver easier to write and maintain.
