    Add support for storing the environment in CFI NOR flash on Juno and FVP
    models.

    I also removed some config values that are not used by CFI flash parts.

    Juno has 1 flash part with 259 sectors. The first 255 sectors are
    0x40000 (256kb) and are followed by 4 sectors of 0x10000 (64KB).

    FVP models simulate a 64MB NOR flash part at base address 0x0FFC0000.
    This part has 256 x 256kb sectors. We use the last sector to store the
    environment.

    To save the NOR flash to a file, the following parameters should be
    passed to the model:

    -C bp.flashloader1.fname=${FILENAME}
    -C bp.flashloader1.fnameWrite=${FILENAME}

    Foundation models don't simulate the NOR flash, but having NOR support
    in the u-boot binary does not harm: attempting to write to the NOR will
    fail gracefully.

    12

    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
