This patch adds the device tree support for FSL LS2085A SoC
based on ARMv8 architecture.
Following levels of DTSI/DTS files have been created for the
LS2085A SoC family:
- fsl-ls2085a.dtsi:
DTS-Include file for FSL LS2085A SoC.
- fsl-ls2085a-simu.dts:
DTS file for FSL LS2085a software simulator model.
In addition, this patch adds build support for FSL's LS2085A
simulator model in arm64 dts Makefile.
