Lists should have fixed amount if items, so add missing constraint to
the 'reg' property (only one address space entry).

The RTL9300 SoC has two I2C controllers. Each of these has an SCL line (which
|
|
if not-used for SCL can be a GPIO). There are 8 common SDA lines that can be
|
|
assigned to either I2C controller.
