ARM: EXYNOS: support Exynos4210-bus Devfreq driver on Nuri board
Support varying voltages:
- GPIODVS for Buck2 is removed.
- Voltage ragne for Buck2 is widen.
Support Buck2 regulator for Exynos4210-bus devfreq driver:
- Added device name for buck2 regulator
- Added exynos4210-busfreq platform device fro Nuri board.
