configs/zynqmp_zcu106_defconfig: move to board rev1.0

Browse Source 
Migrate the zynqmp_zcu106_defconfig to rev1.0 ddr memory, since all new boards
will be using the rev1.0 ddr memory.

This patch also adds documentation in the board/zynqmp/readme.txt explaining
the issue related to the change in ddr memory.  Should users not see anything
printing from the board during boot, the most likely issue is that the board
has the original ddr memory and the u-boot device tree needs to be configured
accordingly to revA.

Original DDR Memory:
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu106-revA"

Where 'sdX' is the device node of the SD.
Eject the SD card, insert it in the board, and power it up.
==============
Important Note
==============
The DDR memory on the original ZCU102 and ZCU106 boards is EOL.
The Buildroot defconfigs for these boards use the new DDR memory
which is configured by the u-boot spl initialization with the
Buildroot config options below.
New DDR Memories:
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu102-rev1.0"
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu106-rev1.0"
If nothing is printing upon boot, most likely it is because the
board has the original DDR memories. To fix the problem, modify
the Buildroot defconfig file to use the u-boot spl initialization
for the original DDR memory using the config below for the target
board.
Original DDR Memories:
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu102-revA"
BR2_TARGET_UBOOT_CUSTOM_MAKEOPTS="DEVICE_TREE=zynqmp-zcu106-revA"
