Automatically register i2c devices from the device tree

The following series adds automatic registration of i2c devices from OF device tree data. If the i2c bus has the of_node pointer set, then it will use that node pointer as the parent for a set of i2c devices and automatically register the child nodes as new i2c devices.

When CONFIG_OF is not set, the of i2c hooks become empty stubs.

Grant Likely (3):
of/i2c: Generalize OF support
i2c: Add OF-style registration and binding
of: refactor of_modalias_node() and remove explicit match table.
