The second CSI-2 C-PHY data-lane have a different line order (BCA) then
the two other data-lanes (ABC) for both connected CSI-2 receivers,
describe this in the device tree.
This have worked in the past as the R-Car CSI-2 driver did not have
documentation for the line order configuration and a magic value was
written to the register for this specific setup. Now the registers
involved are documented and the hardware description as well as the
driver needs to be corrected.

In this change the numerical values for the line-orders are used as the
changes video-interfaces.h are not yet in the renesas tree and it's a
good idea to get this DTS change in the same release as the driver
change.
