Rob Herring fba5618451 dt-bindings: Fix incorrect 'reg' property sizes
The examples template is a 'simple-bus' with a size of 1 cell for
had between 2 and 4 cells which really only errors on I2C or SPI type
devices with a single cell.

The easiest fix in most cases is to change the 'reg' property to for 1 cell
address and size. In some cases with child devices having 2 cells, that
doesn't make sense so a bus node is needed.

description: |+
Renesas R-Car color management module connected to R-Car DU video channels.
It provides image enhancement functions such as 1-D look-up tables (LUT),
3-D look-up tables (CLU), 1D-histogram generation (HGO), and color
space conversion (CSC).
