Subject: [PATCH 3/4] ARM: dts: OMAP5: Add device nodes for ABB

From: "Andrii.Tseglytskyi" <andrii.tseglytskyi@...com>

Add ABB device nodes for OMAP5 family of devices. Data is based on
OMAP543x Technical Reference Manual revision U (April 2013).
NOTE: clock node has been disabled in this patch due to the lack of
OMAP5 clock data.
