The i2c slave disabling is done by mvtwsi driver and is not needed here.

As this comment notes, Turris Omnia needs to migrate to DM_I2C before removing this code. The non DM code path in the mvtwsi driver does not disable the debug I2C client.
Is there a pending patch that enables DM_I2C for Turris Omnia?
