[PATCH 12/19] i2c-nomadik: Register sub-devices when passed via Device Tree

Each I2C device can be correctly probed already using Device Tree,
but the sub-devices still have to be registered by calls to
i2c_register_board_info(). After this patch, each sub-device can
be registered directly from Device Tree instead, removing the
requirement for the aforementioned calls from platform code.
