vexpress64: fvp dram: add DRAM configuration

Browse Source 
Create an additional FVP configuration to boot images pre-loaded into
DRAM.

Sometimes it's preferential to boot the model by loading the files
directly into DRAM via model parameters, rather than using
SemiHosting.

An example of model parmaters that are used to pre-load the files
into DRAM:
    --data cluster0.cpu0=Image@0x80080000 \
    --data cluster0.cpu0=fvp-base-gicv2-psci.dtb@0x83000000 \
    --data cluster0.cpu0=uInitrd@0x84000000

help
This target is derived from TARGET_VEXPRESS64_BASE_FVP and over-rides
the default config to allow the user to load the images directly into
DRAM using model parameters rather than by using semi-hosting to load
the files from the host filesystem.
