This series adds support for the Everest ES7202, a 2-channel PDM
analog-to-digital converter controlled over I2C. Patch 1 adds the DT
bindings and patch 2 the ASoC codec driver.

The driver is based on the Rockchip BSP driver, reworked for mainline to
use regmap and devm_ helpers, probe the device ID, and report the actual
per-step PGA gain.
