ramips: correct WizFi630S pin mappings

WizFi630S had some pins changed in the release version of the board.
The run led, wps button and a slide switch where affected.
This patch is correcting this.
i2c is removed as it is sharing a pin with the run (system) led.
uart2 is enabled as it is also enabled in the OEM firmware.
