[RFC PATCH V2 6/8] ARM: dts: TWL6030/OMAP4: Add OMAP voltage path linkage

[Nishanth Menon]

OMAP4430 and 4460 platforms use TWL6030 to power voltage rails.
However, on 4460, we use twl6030 only for iva and core voltage rails.

Introduce an twl6030_omap4.dtsi to be able to reuse the base definition
for all OMAP4 platforms and the delta change only for panda-es platform
which is based on 4460.
