Add DT bits to support the DH 560-200 display unit, which can be plugged
into the side of the PDK2 board. The display unit contains a display, EDT
ETM0700G0EDH6 and an EDT FT5x06 touchscreen controller.

V2: Add #pwm-cells = <3> to pwm1 node
V3: - Rename polytouch@38 to touchscreen@38
    - Specify FT5406 touchscreen controller
    - Drop legacy linux,wakeup property
