[PATCH 13/15] ARM: ux500: Add support for ab8500 regulators into the Device Tree

[lee.jones@linaro.org (Lee Jones)]

Here we supply the information required to setup regulators
successfully on Snowball and other db8500 variants which use
the ab8500 regulators. This information includes values used
for regulator related register initialisation and platform
specific regulator setup information.
