Samsung pinctrl driver changes for v4.14:
1. Fix NULL pointer dereference on S3C24XX.  This was reported some time ago and
   unfortunately it took few releases to fix.
2. Fix invalid register offset used for external interrupts on Exynos5433.
   This was caused by the same commit as above, although on different path.
3. Consolidate between drivers and bindings the defines for pin mux functions.
4. Minor code improvements.
