[PATCH 1/4] arm: dts: imx28: Use phandles instead of unit addresses

[venkataravi.e@techveda.org (venkataravi.e at techveda.org)]

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

Unit addresses for all peripherals of imx28 are defined in
the corresponding dtsi file, use phandles instead of unit addresses
to reference peripheral nodes in dts files. This makes the DT more
robust and readable.
