This patch adds local Exynos suspend ops and removes all the code left
unnecessary. As a side effect, suspend support on Exynos becomes

CONFIG_PM means that at least one of CONFIG_PM_SLEEP and
CONFIG_PM_RUNTIME is enabled, while multiple entries in
mach-exynos/Kconfig abused it to enable sleep- and runtime-specific

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.

EXYNOS is now Device Tree (DT) only platform so it makes no sense to have

Moreover the kernel image won't even link if neither CONFIG_MACH_EXYNOS4_DT

In 8a4da6e3: "arm: arch_timer: move core to drivers/clocksource", the
selection of ARM_ARCH_TIMER was indirected via HAVE_ARM_ARCH_TIMER,
though mach-exynos's selection of ARM_ARCH_TIMER was missed, and since
then mach-shmobile, mach-tegra, and mach-virt have begun selecting
ARM_ARCH_TIMER. This can lead to architected timer support erroneously
appearing to not be selected in menuconfig.

This reverts commit bd51de53.

Turns out that multiplatform breaks some uses cases, such as when you
have an existing defconfig, since it adds the new EXYNOS_SINGLE config
option as a dependecy. As a result, nearly all exynos config options
will be disabled by default.

Reverting instead of rebasing since this branch is pulled in as a
dependency elsewhere.

This makes it possible to enable the exynos platform as part of a
multiplatform kernel, in addition to keeping the single-platform
exynos support.

The multiplatform variant has a number of limitations at the moment:

* It only supports DT-enabled machines. This is not a problem in
  the long run, as non-DT machines for exynos are going away.
  The main problem here is that the gpio code and the exynos_eint
  irqchip are not multiplatform capable but still required for
  ATAGS based boot.
* The watchdog driver is still missing a conversion.
* sparsemem and memory_holes are currently not supported in
  multiplatform.

The the multiplatform aware ARCH_EXYNOS Kconfig symbol is disabled
for now, as dependent patches are still pending in other
subsystem trees. We will enable it once everything comes together.
Signed-off-by: NArnd Bergmann <arnd@arndb.de>

As a preparation for multiplatform support, this introduces
a new Kconfig symbol to split the ATAGS based EXYNOS platforms
from the DT based ones. Turning off CONFIG_EXYNOS_ATAGS disables
all platforms that are not yet converted to DT, and we can
have code that relies on DT checking for this symbol being
disabled.

The TWD and SCU configs are selected by default as long as
MSM_SCORPIONMP is false and/or MCT is false. Implementing the
logic this way certainly saves lines in the Kconfig but it
precludes those machines which select MSM_SCORPIONMP or MCT from
participating in the single zImage effort because when those
machines are combined with other SMP capable machines the TWD and
SCU are no longer selected by default.

Push the select out to the machine entries so that we can compile
these machines together and still select the appropriate configs.

it would be appropriate to rename the function 'exynos4_timer_init'
