This adds a i2c-mux-pinctrl node to dove.dtsi for the internal i2c mux found on Dove SoCs. Up to now, we had no board using any of the two additional i2c busses, so make sure the change does not break any existing boards. Therefore, we rename the i2c-controller node label to "i2c" and enable it by default. Also, the dedicated sub-bus (now "i2c0") is enabled by default. The two optional sub-busses require additional external pin-muxing, so disable them by default.
