    arm-exynos4: add regulator fix patches for SMDK310 and Origen boards
    
    Without those patches, both drivers oopses, due to a bug at the
    dummy regulator on Kernel 3.6.
    
    Also, some board components don't work without it.
    
    Those patches could not be 100% correct, but all components that
    are known to work with the upstream Kernel are available with it.
