Subject: [PATCH v2 2/2] ARM: dts: r8a7742-iwg21d-q7-dbcm-ca: Add support for 8-bit ov7725 sensors

The 8-bit ov7725 sensors can also be connected to the camera daughter
board.

This patch creates a separate dtsi file for ov7725 sensors and is included
in r8a7742-iwg21d-q7-dbcm-ca.dts (which is commented out as by default
ov5640 is enabled)
