Subject: [PATCH 2/4] arm: dts: imx28: Remove system bus unit addresses

From: Ravi Eluri <venkataravi.e@...hveda.org>

Unit addresses for the system buses of imx28 are defined in
the corresponding dtsi file. Any peripheral node on APBH, APBX
and AHB busses can be accessed via phandle. Removed duplicate
system bus unit address entries, this makes the DT more robust
and readable.
