Samsung PM related 2nd updates for v3.15

 From Tomasz Figa <t.figa@samsung.com>:
Current Samsung PM code is heavily unprepared for multiplatform
systems. The design implies accessing functions and global
variables defined in particular mach- subdirectory from common
code in plat-, which is not allowed when building ARCH_MULTIPLATFORM.
In addition there is a lot of forced code unification, which makes
common function handle any possible quirks of all supported SoCs.
In the end this design turned out to not work too well, ending with
a lot of empty functions exported from mach-, just because code in
common pm.c calls them. Moreover, recent trend of moving lower level
suspend/resume code to proper drivers, like pinctrl or clk, made a
lot of code there redundant, especially on DT-only platforms like
Exynos.

Note that this branch is based on previous tags/samsung-pm-1 and merge
tags/samsung-cleanup-2 because of fix build error from recent changes
of <linux/serial_s3c.h>
