ASoC: samsung: Add driver for Aries boards

Samsung Aries boards have a WM8994 codec connected to the Samsung
I2S controller, the BT codec, and the cellular modem.  Jack detection
is done by a combination of an ADC, GPIOs, and an extcon device for
the USB dock.  There is also a GPIO for selection between the Mic
path and the TV out path on the headphone jack.

There are two main variants, one with an FM radio and where the modem
is the master and one without a radio and the modem is the slave.
