Exynos pinctrl drivers contain pretty big per-SoC data structures. The pinctrl-exynos object file contained code and data for both ARMv7 and ARMv8 SoCs thus it grew big. There will not be a shared image between ARMv7 and ARMv8 so there is no need to combine all of this into one driver. Splitting the data allows to make it more granular (e.g. code related to ARMv8 Exynos is self-contained), slightly speed up the compilation and reduce the effective size of compiled kernel. The common data structures and functions reside still in existing pinctrl-exynos.c. Only the SoC-specific parts were moved out to new files. Except marking few functions non-static and adding them to header, there were no functional changes in the code.
