Jon Smirl 2526c151c3 drivers/of: Add the of_find_i2c_device_by_node function.
The of_find_i2c_device_by_node function allows you to follow a
reference in the device tree to an i2c device node and then locate
the linux device instantiated by the device tree. Example use: an I2S
bus driver finding the i2c_device instance for a codec described by
a device tree node.

This was waiting for Anton's i2c patches that were just added.

Jochen Friedrich 8af302e2dc [POWERPC] Fix of_i2c include for module compilation
Remove #ifdef CONFIG_OF_I2C as this breaks module compilation.
Drivers using this header should depend on OF_I2C anyways, so
there's no need to make this conditional.
