Remove support for legacy VE memory map in FVP 

This patch removes support for legacy Versatile Express memory map for the
GIC peripheral in the FVP platform. The user guide is also updated for the
same.

* The Firmware Image Package is loaded at the start of NOR FLASH0.
* The Linux kernel image and device tree are loaded in DRAM.
* The default use-case for the Foundation FVP is to use the `--gicv3` option
and enable the GICv3 device in the model. Note that without this option,
the Foundation FVP defaults to legacy (Versatile Express) memory map which
is not supported by ARM Trusted Firmware.

### Configuring the GICv2 memory map
The Base FVP models support GICv2 with the default model parameters at the
following addresses. The Foundation FVP also supports these addresses when
configured for GICv3 in GICv2 emulation mode.
GICv2 Distributor Interface 0x2f000000
GICv2 CPU Interface 0x2c000000
GICv2 Virtual CPU Interface 0x2c010000
GICv2 Hypervisor Interface 0x2c02f000
The AEMv8 Base FVP can be configured to support GICv2 at addresses
corresponding to the legacy (Versatile Express) memory map as follows. These are
the default addresses when using the Foundation FVP in GICv2 mode.
GICv2 Distributor Interface 0x2c001000
GICv2 CPU Interface 0x2c002000
GICv2 Virtual CPU Interface 0x2c004000
GICv2 Hypervisor Interface 0x2c006000
The choice of memory map is reflected in the build variant field (bits[15:12])
in the `SYS_ID` register (Offset `0x0`) in the Versatile Express System
registers memory map (`0x1c010000`).
* `SYS_ID.Build[15:12]`
`0x1` corresponds to the presence of the Base GIC memory map. This is the
default value on the Base FVPs.
* `SYS_ID.Build[15:12]`
`0x0` corresponds to the presence of the Legacy VE GIC memory map. This is
the default value on the Foundation FVP.
This register can be configured as described in the following sections.
NOTE: If the legacy VE GIC memory map is used, then Trusted Firmware must be
compiled with the GICv2 only driver, and the corresponding FDT and BL33 images
should be used.
#### Configuring AEMv8 Foundation FVP GIC for legacy VE memory map
The following parameters configure the Foundation FVP to use GICv2 with the
legacy VE memory map:
<path-to>/Foundation_Platform \
--cores=4 \
--secure-memory \
--visualization \
--no-gicv3 \
--data="<path-to>/<bl1-binary>"@0x0 \
--data="<path-to>/<FIP-binary>"@0x8000000 \
--block-device="<path-to>/<file-system-image>"
Explicit configuration of the `SYS_ID` register is not required.
#### Configuring AEMv8 Base FVP GIC for legacy VE memory map
The following parameters configure the AEMv8 Base FVP to use GICv2 with the
legacy VE memory map. They must added to the parameters described in the
"Running on the AEMv8 Base FVP" section above:
-C cluster0.gic.GICD-offset=0x1000 \
-C cluster0.gic.GICC-offset=0x2000 \
-C cluster0.gic.GICH-offset=0x4000 \
-C cluster0.gic.GICH-other-CPU-offset=0x5000 \
-C cluster0.gic.GICV-offset=0x6000 \
-C cluster0.gic.PERIPH-size=0x8000 \
-C cluster1.gic.GICD-offset=0x1000 \
-C cluster1.gic.GICC-offset=0x2000 \
-C cluster1.gic.GICH-offset=0x4000 \
-C cluster1.gic.GICH-other-CPU-offset=0x5000 \
-C cluster1.gic.GICV-offset=0x6000 \
-C cluster1.gic.PERIPH-size=0x8000 \
-C gic_distributor.GICD-alias=0x2c001000 \
-C gicv3.gicv2-only=1 \
-C bp.variant=0x0
The `bp.variant` parameter corresponds to the build variant field of the
`SYS_ID` register. Setting this to `0x0` allows the ARM Trusted Firmware to
detect the legacy VE memory map while configuring the GIC.
