armv8: ls1088a: Add NXP LS1088A SoC support

The QorIQ LS1088A processor is built on the Layerscape
architecture combining eight ARM A53 processor cores
with advanced, high-performance datapath acceleration
and networks, peripheral interfaces required for
networking, wireless infrastructure, and general-purpose
embedded applications.

LS1088A is compliant with the Layerscape Chassis Generation 3.

Features summary:
 - Eight 32-bit / 64-bit ARM v8 Cortex-A53 CPUs
 - Cores are in 2 cluster of 4-cores each
 - Cache coherent interconnect (CCI-400)
 - One 64-bit DDR4 SDRAM memory controller with ECC
 - Data path acceleration architecture 2.0 (DPAA2)
 - Ethernet interfaces: SGMIIs, RGMIIs, QSGMIIs, XFIs
 - QSPI, IFC, 3 PCIe, 1 SATA, 2 USB, 1 SDXC, 2 DUARTs etc
