The OMAP4 SoC family uses specially-designed
PMIC (power management IC) companion chip for power
management needs: TWL6030/TWL6032.
Therefore there is a typical connection of PMIC to OMAP4
so we can figure it out into separate .dtsi file
and do not duplicate over board-specific files.
Tested on OMAP4 SDP board and compile-tested for Panda board
