This patch makes the 2nd DRAM bank available on Juno only and not on
other vexpress64 targets, eg. the FVP models.
The commit below added a 2nd bank of NOR flash for Juno, but also for
all vexpress64 targets:

vexpress64: Juno: Declare all 8GB of RAM and make them visible to the
kernel.
Juno comes with 8GB RAM, but U-Boot only passes 2GB to the kernel.
Declare a secondary memory bank and set the sizes correctly.

Unfortunately, I only fully tested on Juno R0, R1 and the FVP Foundation
model. Whilst FVP Base AEMV8 models run U-Boot OK, they fail to boot
the kernel.
