A number of boards produced by OpenGear and based on the Micrel KS8695 SoC.
Add board support to the KS8695 kernel code to support them.

The following machine type entries will need to be added back into the
mach-types file with these in mainline:

    cm4008      MACH_CM4008       CM4008       624
    cm41xx      MACH_CM41XX       CM41XX       672
    cm4002      MACH_CM4002       CM4002       876
    im42xx      MACH_IM42XX       IM42XX       1105
    im4004      MACH_IM4004       IM4004       1400
