Subject: [PATCH v3 3/5] ASoC: da7218: Use i2c_get_match_data()

Use preferred i2c_get_match_data() instead of of_match_device() and
i2c_match_id() to get the driver match data. With this, adjust the
includes to explicitly include the correct headers.

Avoid using 0 for enum da7218_dev_id so that no match data can be
distinguished.
