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.
