Subject: dm: exynos: dts: Adjust device tree files for U-Boot

The pinctrl bindings used by Linux are an incomplete description of the
hardware. It is possible in most cases to determine the register address
of each, but not in all cases. By adding an additional property we can
fix this, and avoid adding a table to U-Boot for every single Exynos
SOC.
