arm64: dts: Add support for NXP LS1028A SoC

LS1028A contains two ARM v8 CortexA72 processor cores
with 32 KB L1-D cache and 48 KB L1-I cache

Features summary
 Two 32-bit / 64-bit ARM v8 Cortex-A72 CPUs
  - Arranged as single clusters of two cores sharing a 1 MB L2 cache
  - Speed Up to 1.3 GHz
  - Support for cluster power-gating.
 Cache coherent interconnect (CCI-400)
  - Hardware-managed data coherency
  - Up to 400 MHz
 32-bit DDR4 SDRAM memory controller with ECC
 Two PCIe 3.0 controllers
 One serial ATA (SATA 3.0) controller
 Two high-speed USB 3.0 controllers with integrated PHY

 Following levels of DTSI/DTS files have been created for the LS1028A
  SoC family:

         - fsl-ls1028a.dtsi:
                 DTS-Include file for NXP LS1028A SoC.

         - fsl-ls1028a-qds.dts:
                 DTS file for NXP LS1028A QDS board.

         - fsl-ls1028a-rdb.dts:
                 DTS file for NXP LS1028A RDB board
