Add a simple custom voltage regulator coupler for Exynos5800 SoCs, which require coupling between "vdd_arm" and "vdd_int" regulators. This coupler ensures that the voltage values don't go below the bootloader-selected operation point during the boot process until the clients set their constraints. It is achieved by assuming minimal voltage value equal to the current value if no constraints are set. This also ensures proper voltage balancing if any of the client driver is missing. The balancing code comes from the regulator/core.c with the additional logic for handling regulators without client constraints applied added.
