arm: zynqmp: Add ZynqMP minimal R5 support

Xilinx ZynqMP also contains dual Cortex R5 which can run U-Boot.
This patch is adding minimal support to get U-Boot boot.
U-Boot on R5 runs out of DDR with default configuration that's why
DDR needs to be partitioned if there is something else running on arm64.
Console is done via Cadence uart driver and the first Cadence Triple
Timer Counter is used for time.

This configuration with uart1 was tested on zcu100-revC.

There are two ways how to run this on ZynqMP.
1. Run from ZynqMP arm64
tftpb 20000000 u-boot-r5.elf
setenv autostart no && bootelf -p 20000000
cpu 4 disable && cpu 4 release 10000000 lockstep
or
cpu 4 disable && cpu 4 release 10000000 split

2. Load via jtag when directly to R5
