arm64: zynqmp: add support for Avnet UltraZed-EV Starter Kit

Avnet UltraZed-EV Starter Kit is composed by the UltraZed-EV SoM and the
only publicly-available compatible carrier card. The SoM is based on the EV
version of the Xilinx ZynqMP SoC+FPGA.

The psu_init_gpl.c file has been generated from the board definition files
at [0] using Vivado 2018.3 and then minimized by
tools/zynqmp_psu_init_minimize.sh. Manually removed serdes init code since
it is not mentioned in device tree and fixed a checkpatch error.
