SPM(BL32) and hafnium(BL33) expect their manifest base address in x0

As secondary cores show up, they populate an array to

The Power Domain Tree Description is populated with
a topology based on the maximum harcoded values.

In BL2, fw_config's population happened before the cache gets

Hence to boost the performance, moved fw_config's population
after cache gets enabled (i.e. after MMU gets enabled).

BL2 size gets increased due to the libfdt library update and

arm_fpga: Predefine DTB and BL33 load addresses ...

The memory layout for the FPGA is fairly uniform for most of the FPGA
images, and we already assume that DRAM starts at 2GB by default.

Prepopulate PRELOADED_BL33_BASE and FPGA_PRELOADED_DTB_BASE to some
sane default values, to simplify building some stock image.
If people want to deviate from that, they can always override those
addresses on the make command line.

corstone700: splitting the platform support into FVP and FPGA ...

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
