This adds I2C[1245] busses support to Koelsch board.
I2C[03] do not have any slave devices connected and
are not used because of the following:
* I2C0 pins are multiplexed with LBSC pins;
* I2C3 pins are multiplexed with EtherMAC and VIN0 pins.

This adds VIN1 SoC camera along with ADV7180 subdevice support to Koelsch.
VIN0 camera is not registered because it has ADV7612 I2C subdevice
which is not supported yet.

As for the Lager patch, you can make this function static.
