vexpress64: use 2nd DRAM bank only on juno
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.
