Enable the controller at the tested 400 kHz bus frequency. Its GPIO2_A2 and GPIO2_A3 pinmux is provided by rk3308.dtsi. Keep the bus enablement separate from the touchscreen device node so it can be reviewed without depending on the pending NS2009 binding and driver. The controller-only configuration was booted on M10 V1.2 with no NS2009 device instantiated.
