According to v4l2 dt document, we add:
  a camera host: ISI port.
  a i2c camera sensor: ov2640 port.
to sama5d3xmb.dtsi.

The ov2640 node defines the pinctrls, clocks and refer to isi port.
The ISI node also has a reference to the ov2640 port.

v1 -> v2:
  1. move the chip common part of ISI DT node to sama5d3.dtsi.
  2. the pck1 pinctrl name is changed.
