Merge "Samsung cleanup for v3.17" from Kukjin Kim:

Most of them are for exynos SoCs, remove useless codes and update for
PMU consolidation.

- remove unnecessary header file in mach-exynos/pmu.c
- remove unused code in mach-exynos/common.h
- remove mach-exynos/regs-pmu.h dependency from PD
- remove file path from comment section in mach-exynos

- move SYSREG definitions into mach-exynos/regs-sys.h

- add mapping PMU base address via DT for PMU cleanup

- use staic in mach-exynos/common.h
- update Samsung UART config options for low-level debug
