If DM_I2C is used, the command "i2c dev" will not reassign gd->cur_i2c_bus.
Add this bus option to change the active I2C bus.

This driver should be converted to driver model.
It has been. See drivers/gpio/pca953x_gpio.c
I mean that it should use dm_i2c_read() instead of i2c_read(), so that the problems of an 'active' i2c bus go away. Also it should use devicetree.
