This patch set adds support for the Everest-semi ES8311 codec.

Everest-semi ES8311 codec is a low-power mono audio codec with I2S audio
interface and I2C control.

Implemented and tested most of the codec features, with few limitations
listed in the driver commit message. The test setup was composed of a
ESP32-LyraT-Mini board, which embeds the codec, connected via I2C and
I2S to a Raspberry Pi Zero W host board. Some tests were also performed
on a Pine64 A64 host board (e.g. to test the suspend/resume not
supported by the rpi). The codec driver was bound with the simple-card
driver running on kernel v6.9-rc7.
