[PATCH v1 1/5] ASoC: codec: adau1977-i2c: Add OF device match table

[Mohammad Rafi Shaik]

The ADAU1977 I2C driver lacks an OF device match table, preventing
it from binding to codec instances described via Device Tree. Systems
using compatible strings such as "adi,adau1977", "adi,adau1978", or
"adi,adau1979" fail to probe the driver as a result.

Add a descriptive prompt string for SND_SOC_ADAU1977_I2C/SPI so
the driver is visible and selectable when running menuconfig.
