[PATCH v2 1/4] ARM: dts: omap: omap4-epson-embt2ws: define GPIO regulators

[Andreas Kemnade]

To properly have things running after cold boot, define
GPIO regulators. Naming is based on board file.

In the vendor kernel they are enabled in a function
called bt2ws_dcdc_init() if the system is not booted just
to charge the battery.
