[PATCH v2 1/2] ARM: at91: dts: add isi & ov2640 dt nodes for at91sam9m10g45ek board

[Josh Wu]

First we group the isi data pins, and for now we only use 0~7 data pins
with HSYNC and VSYNC.
Also add the link for atmel-isi and ov2640 sensor node.

Signed-off-by: Josh Wu <josh.wu at atmel.com>

Changes in v2:
- group the isi data pin.
- remove the isi_mck pin from pinctrl-isi as it will used by camera
  sensor.
