This adds a device-tree definition for the CSI0 MCLK pin,
which can be used for feeding MIPI CSI-2 sensors.

Is this used anywhere? Current policy is to add pin definitions only if any 
user exists.

Ah right, sorry. I'll resend this when adding a board that uses it!

IIRC we sort of loosened that requirement with the use of /omit-if-no-ref/.
The A20 dtsi file has a whole bunch of pins defined that are not directly
used but are available for users to reference, especially in overlays.
The "-@" parameter for the device tree compiler, used to build overlay
compatible DTBs, makes the compiler ignore /omit-if-no-ref/ and include
all the nodes.
