Enables the OV5642 parallel-bus sensor, and the OV5640 MIPI CSI-2 sensor.
Both hang off the same i2c2 bus, so they require different (and non-
default) i2c slave addresses.

The OV5642 connects to the parallel-bus mux input port on ipu1_csi0_mux.

The OV5640 connects to the input port on the MIPI CSI-2 receiver on
mipi_csi. It is set to transmit over MIPI virtual channel 1.

Note there is a pin conflict with GPIO6. This pin functions as a power
input pin to the OV5642, but ENET uses it as the h/w workaround for
erratum ERR006687, to wake-up the ARM cores on normal RX and TX packet
done events (see 6261c4c8). So workaround 6261c4c8 is reverted here to
support the OV5642, and the "fsl,err006687-workaround-present" boolean
also must be removed. The result is that the CPUidle driver will no longer
allow entering the deep idle states on the sabrelite.

For me it sounds like a candidate of its own separate change.

Yes, I split out the two partial reverts into a separate commit
("ARM: dts: imx6qdl-sabrelite: remove erratum ERR006687
  workaround").

Please reorder device nodes by address value,

done.

  also according to ePAPR
node names should be generic, labels can be specific:

	ov5640: camera at 40 {
		...
	};

	ov5642: camera at 42 {
		...
	};

fixed.

Indentation issues above, please use tabs instead of spaces.

fixed.

Also please add new pin control groups preserving the alphanimerical order.

done.
