Defines the host video capture device node and an OV5642 camera sensor
node on i2c2. The host capture device connects to the OV5642 via the
parallel-bus mux input on the ipu1_csi0_mux.
Note there is a pin conflict with GPIO6. This pin functions as a power
input pin to the OV5642, but ENET requires it to wake-up the ARM cores
on normal RX and TX packet done events (see 6261c4c8). So by default,
capture is disabled, enable by uncommenting __OV5642_CAPTURE__ macro.
Ethernet will still work just not quite as well.
