2c793fa349 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>

The big series refactoring Exynos suspend to RAM handling missed the

including old mach/pm_core.h header and using old s3c_cpu_resume symbol
instead of new exynos_cpu_resume, resulting in compilation failures with

functionality.

This patch fixes this abuse by replacing dependencies on CONFIG_PM with
appropriate dependencies on either CONFIG_PM_SLEEP or CONFIG_PM_RUNTIME,
whichever is appropriate.

The detour through plat-versatile/sched-clock.c is hard to migrate

so let's just inline the sched_clock registration and cut one more
dependency to plat-versatile.

This also makes this sched_clock implementation compulsory.
