[PATCH v2 2/4] ARM: dts: omap: omap4-epson-embt2ws: wire up regulators

[Andreas Kemnade <andreas@kemnade.info>]

Wire up the regulators where usage is plausible. Do not
wire them if purpose/usage is unclear like 5V for
many things requiring lower voltages.

Tested on vendor kernel that backlight definitively does not react
on blc_[rl] GPIOs.
