[PATCH] powerpc: fsl_soc: Pre-allocate i2c bus number and pre-register devices.

[Scott Wood <scottwood@freescale.com>]

A bus number is dynamically allocated, used to register devices
with i2c_register_board_info(), and then passed to the i2c-mpc
driver to use with i2c_add_prenumbered_adapter().

Signed-off-by: Scott Wood <scottwood@freescale.com>

This supersedes the "Call of_register_i2c_devices() for	fsl-i2c" patch.
