Add a devicetree overlay to support the official Raspberry Pi 7inch touchscreen. This also demuxes the i2c0 controller to support both pinctrls. Changes in v2: * The device tree in now an overlay * The i2c demux patch is kept for now to have a working patch set. It has not been merged yet in [1]. * The device tree overlay doesn't use fragments. It is working as is but not enough literature was found to go one way or the other.
