Adjust the regex for child-node address to account for the fact that
RTL9310 supports 12 instead of only 8 SDA lines. Also, narrow this per
variant.
Add a vendor-specific property to explicitly specify the
Realtek-internal ID of the defined I2C controller/master. This is
required, in particular for RTL9310, to describe the correct I2C
master. Require this property for RTL9310.
Add compatibles for known SoC variants RTL9311, RTL9312 and RTL9313.
