Handling System MMUs with an identifier is not flexible to manage
System MMU platform devices because of the following reasons:
1. A device driver which needs to handle System MMU must know the ID.
2. A System MMU may not present in some implementations of Exynos family.
3. Handling System MMU with IOMMU API does not require an ID.
This patch is the result of removing ID of System MMUs.
Instead, a device driver that needs to handle its System MMU must
use IOMMU API while its descriptor of platform device is given.
This patch also includes the following enhancements:
- A System MMU device becomes a child if its power domain device.
- clkdev

This branch contains a handful of updates of SoC base code that had
dependencies on other external trees that have now been merged:
* Support for the new EXYNOS5250 SoC from Samsung
* SMP and power domain support for Tegra3 from NVIDIA
* ux500 updates for exporting SoC information through sysfs

Add support for generic power domain for Exynos4 platforms and remove the
Samsung specific power domain control for Exynos4.
The generic power domain infrastructure is used to control the power domains
available on Exynos4. For non-dt platforms, the power domains are statically
instantiated. For dt platforms, the power domain nodes found in the device
tree are instantiated.

The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.
This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.
