[PATCH 3/3][v2] arm64: Add DTS support for FSL's LS2088A SoC

[Abhimanyu Saini <abhimanyu.saini-3arQi8VN3Tc@public.gmane.org>]

This patch adds the device tree support for FSL LS2088A SoC based on
ARMv8 architecture.

Following levels of DTSI/DTS files have been created for the LS2088A
SoC family:

     - fsl-ls2088a.dtsi:
            DTS-Include file for FSL LS2088A SoC.

     - fsl-ls2088a-qds.dts:
            DTS file for FSL LS2088A QDS board.

     - fsl-ls2088a-rdb.dts:
            DTS file for FSL LS2088A RDB board.

Changes for v2:
	- reorganize LS2088A device tree to use common
	  nodes from LS2080A device trees.
