    i2c: some overdue driver removal
    
    This patch contains the overdue removal of three I2C drivers.
    
    [JD: In fact only i2c-ixp4xx can be removed at the moment, the other two
    platforms don't implement the generic GPIO layer yet.]

- * Intel's IXP4xx XScale NPU chipsets (IXP420, 421, 422, 425) do not have
- * an on board I2C controller but provide 16 GPIO pins that are often
- * used to create an I2C bus. This driver provides an i2c_adapter 
- * interface that plugs in under algo_bit and drives the GPIO pins

- * NOTE: Since different platforms will use different GPIO pins for

- *       pointer to pass the GPIO numbers to the driver. This 
- *       allows us to support all the different IXP4xx platforms
- *       w/o having to put #ifdefs in this driver.
- *
- *       See arch/arm/mach-ixp4xx/ixdp425.c for an example of building a 
- *       device list and filling in the ixp4xx_i2c_pins data structure 
- *       that is passed as the platform_data to this driver.
