dts: i2c: Add missing #address-cell & #size-cell properties

Browse source 
The I2C controller nodes are the root of the I2C bus for that controller
and thus may have children nodes that represent the I2C devices on that
controller.  Thus we need to specify the #address-cell & #size-cell
properties.
