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.
