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 v4:
- Incorporated Shawn's comments by reorganizing
DTSI, moving all include definations to the top
- add missing files
Changes for v2:
- reorganize LS2088A device tree to use common
nodes from LS2080A device trees.
