This patch:

   * Bumps the PSCI VERSION to 1.0. This means that
     the PSCI_VERSION API will now return the value 0x00010000
     to indicate the version as 1.0. The firmware remains
     compatible with PSCI v0.2 clients.

   * The firmware design guide is updated to document the
     APIs supported by the Trusted Firmware generic code.

   * The FVP Device Tree Sources (dts) and Blobs(dtb) are also
     updated to add "psci-1.0" and "psci-0.2" to the list of
     compatible PSCI versions.

This patch updates the representation of idle tables and cpu/cluster topology in
the device tree source files for the FVP to what the latest cpuidle driver in
Linux expects. The device tree binaries have also been updated.

TZC-400 is configured to set the last 16MB of DRAM1 as secure memory and
the rest of DRAM as non-secure. Non-secure software must not attempt to
access the 16MB secure area.

Device tree files (sources and binaries) have been updated to match this
configuration, removing that memory from the Linux physical memory map.

To use UEFI and Linux with this patch, the latest version of UEFI and
the updated device tree files are required. Check the user guide in the
documentation for more details.

Replaced magic numbers with #define for memory region definition in the
platform security initialization function.

Fixes ARM-software/tf-issues#149

- Use the TrustZone controller on Base FVP to program DRAM access
  permissions. By default no access to DRAM is allowed if
  'secure memory' is enabled on the Base FVP.
- The Foundation FVP does not have a TrustZone controller but instead
  has fixed access permissions.
- Update FDTs for Linux to use timers at the correct security level.
- Starting the FVPs with 'secure memory' disabled is also supported.

Limitations:
Virtio currently uses a reserved NSAID. This will be corrected in
future FVP releases.

- The interrupt addresses need to be updated to work.

- The Foundation FVP is a cut down version of the Base FVP and as
  such lacks some components.
- Three FDTs are provided.
  fvp-foundation-gicv2legacy-psci:
    Use this when setting the Foundation FVP to use GICv2. In this
    mode the GIC is located at the VE location, as described in the
    VE platform memory map.
  fvp-foundation-gicv3-psci :
    Use this when setting the Foundation FVP to use GICv3. In this
    mode the GIC is located at the Base location, as described in the
    Base platform memory map.
  fvp-foundation-gicv2-psci :
    Use this when setting the Foundation FVP to use GICv3, but Linux
    is expected to use GICv2 emulation mode. In this mode the GIC is
    located at the Base location, but the GICv3 is used in GICv2
    emulation mode.
