ARM: EXYNOS: Fix build with PM_SLEEP=n and ARM_EXYNOS_CPUIDLE=y

Fix building of exynos_defconfig with CONFIG_PM_SLEEP disabled and
CONFIG_ARM_EXYNOS_CPUIDLE enabled by:

* adding EXYNOS_CPU_SUSPEND config option
* always building sleep.o
* building pm.o if EXYNOS_CPU_SUSPEND is enabled
* moving suspend specific code from pm.c to suspend.c
* enabling pm-common.o build also for EXYNOS_CPU_SUSPEND option

[ Please note that there are no changes in the code moved from pm.c
to suspend.c except making few functions non-static and cleaning
up includes. ]

Also while at it update Copyright dates.

ARM: EXYNOS: Add support for firmware-assisted suspend/resume

On a numer of Exynos-based boards Linux kernel is running in non-secure
mode under a secure firmware. This means that certain operations need to
be handled in special way, with firmware assistance. System-wide
suspend/resume is an example of such operations.

This patch adds support for firmware-assisted suspend/resume by
leveraging recently introduced suspend and resume firmware operations
and modifying existing suspend/resume paths to account for presence of
secure firmware.

ARM: EXYNOS: Move code from hotplug.c to platsmp.c

Cleanup a little the SMP/hotplug code for Exynos by:
1. Moving completely all functions from hotplug.c into the platsmp.c;
2. Deleting the hotplug.c file.

After recent cleanups (e.g. 75ad2ab28f0f "ARM: EXYNOS: use
v7_exit_coherency_flush macro for cache disabling") there was only CPU
power down related code in hotplug.c file.

Rationale behind the code movement and benefits:
1. The file platsmp.c is the only user of code located in hotplug.c.
Keeping code in hotplug.c required declaring exynos_cpu_die() in common.h.
Such dependencies and mentioned exynos_cpu_die() declaration can be
removed.
2. In next patches exynos_set_delayed_reset_assertion() will be
introduced. This function will be called by:
- cpu_leave_power (hotplug.c),
- platform_do_lowpower (hotplug.c),
- exynos_boot_secondary (platsmp.c).

Merging hotplug.c into platsmp.c leads to simpler and cleaner code with
less dependencies between files.

The commit only moves code around with one additional observable change:
the hotplug.c was compiled with custom CFLAGS (-march=armv7-a). These
CFLAGS are not necessary any more.

Pull ARM SoC driver changes from Olof Johansson:
"SoC-near driver changes that we're merging through our tree. Mostly
because they depend on other changes we have staged, but in some cases
because the driver maintainers preferred that we did it this way.

This contains a largeish cleanup series of the omap_l3_noc bus driver,
cpuidle rework for Exynos, some reset driver conversions and a long
branch of TI EDMA fixes and cleanups, with more to come next release.

The TI EDMA cleanups is a shared branch with the dmaengine tree, with
a handful of Davinci-specific fixes on top.

After discussion at last year's KS (and some more on the mailing
lists), we are here adding a drivers/soc directory. The purpose of
this is to keep per-vendor shared code that's needed by different
drivers but that doesn't fit into the MFD (nor drivers/platform)
model. We expect to keep merging contents for this hierarchy through
arm-soc so we can keep an eye on what the vendors keep adding here and
not making it a free-for-all to shove in crazy stuff"

Pull part one of ARM SoC updates from Olof Johansson:
"A quite large set of SoC updates this cycle. In no particular order:

- Multi-cluster power management for Samsung Exynos, adding support
for big.LITTLE CPU switching on EXYNOS5

- SMP support for Marvell Armada 375 and 38x

- SMP rework on Allwinner A31

- Xilinx Zynq support for SOC_BUS, big endian

- Marvell orion5x platform cleanup, modernizing the implementation
and moving to DT.

- _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
that their platform can be enabled in the same kernel binary as
most of the other v7 platforms in the tree. \o/

The work isn't quite complete, there's some driver fixes still
needed, but the basics now work.

New SoC support added:

- Freescale i.MX6SX

- LSI Axxia AXM55xx SoCs

- Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800

- STi STIH407

plus a large set of various smaller updates for different platforms.
I'm probably missing some important one here"
