[PATCH v4 14/14] ARM: dts: Configure regulators for suspend on exynos Peach boards
The regulator core now has support to choose if a regulator
has to be enabled or disabled during system suspend and also
the supports changing the regulator operating mode during
runtime and when the system enters into sleep mode.
To lower power during suspend, configure the regulators state
using the same configuration found in the ChromeOS 3.8 kernel.

Changes in v4: None
Changes in v3:
- Use the standard suspend state binding as suggested by Mark Brown.
