This patch performs the following:

- Creating two corstone700 platforms under corstone700 board:

  fvp and fpga

- Since the FVP and FPGA have IP differences, this commit provides a specific DTS for each platform
- The platform can be specified using the TARGET_PLATFORM Makefile variable
(possible values are: fvp or fpga)
- Allowing to use u-boot by:
  - Enabling NEED_BL33 option
  - Fixing non-secure image base: For no preloaded bl33 we want to
    have the NS base set on shared ram. Setup a memory map region
    for NS in shared map and set the bl33 address in the area.
- Setting the SYS_COUNTER_FREQ_IN_TICKS based on the selected
platform
- Setting ARM_MAP_SHARED_RAM and ARM_MAP_NS_SHARED_RAM to use MT_MEMORY

Adding support for generating a semi-random number required for
enabling building TF-A with stack protector support.
TF-A for corstone-700 may now be built using ENABLE_STACK_PROTECTOR=all

This patch adds support for Corstone-700 foundation IP, which integrates
both Cortex-M0+ and Cortex-A(Host) processors in one handy, flexible
subsystem.
This is an example implementation of Corstone-700 IP host firmware.

Cortex-M0+ will take care of boot stages 1 and 2(BL1/BL2) as well as
bringing Host out RESET. Host will start execution directly from BL32 and
then will jump to Linux.

It is an initial port and additional features are expected to be added
later.
