[PATCH V2 0/2] ARM: SAMSUNG: Add Support Power Domain Control

[Kukjin Kim]

This patch adds support Power Domain Control based on Runtim PM.

Each Power Domain is represented by a Power Domain device and the devices
belong to these Power Domains should be set as a child device of the Power
Domain devices. The corresponding drivers of the devices should implement
Runtime PM to control the Power Domains.

Changes since V1:
- Removed calling of 'samsung_pd_init()' from machine specific code to arch_initcall as Ben's suggestion.
- Use "base" variable in platform data instead of using long switch case statement as Marek's suggestion.
- Add GPS power domain.
