This series adds support for hardware designs where multiple I2C
gpio based busses are realized with dedicated SDA lines and a
shared SCL line. This way N busses can be realized with N+1 gpios.

Currently there are several Realtek switches that make use of 
this design. Samples are:

HPE 1920-48G
Linksys LGS310C
Zyxel GS1920-24
Engenius EWS2910
D-Link DGS-1250
