[PATCH 1/3] i2c: set adapter.nr explicitly to -1

[Sascha Hauer]

dev->id will always be -1 for device tree instantiated devices. Instead
of setting adapter.nr to dev->id, set it to -1 explicitly for all I2C
bus drivers that are purely instantiated from device tree.

This is done for clarity just to show that all I2C bus numbers are
really dynamically assigned.
