Allow the ssm2602/ssm2603/ssm2604 codec driver to be instantiated from the device tree. Also, add Kconfig prompts to allow manual selection of both the I2C and SPI configuration versions of the driver. Signed-off-by: Stefan Kristiansson <stefan.kristiansson@xxxxxxxxxxxxx>
Looks mostly good, but you should Cc both the devicetree and the ASoC maintainers.

Since the driver is supposed to behave different depending on the device you should set the driver data similar to like it is done in the ssm2602_i2c_id table and add code in the probe function to extract the driver data.

The ssm2603 and ssm2604 do not have a SPI interface.
