v3:
 - create device-tree parsing helper functions
 - update the .dsc file layout to minimize the modification
 - remove unnesessary blank line updates

v2:
 - get aligned to the tf-a update, it supports 512 cores
   and memory map is updated.

  SbsaQemu: Build infrastructure for StandaloneMm image
  SbsaQemu: add MM based UEFI secure boot support
  SbsaQemu: add standalone MM build instruction
  SbsaQemu: fix typo

Add the build infrastructure for compilation of StandaloneMm image.
SbsaQemu.fdf is modified to extend the FLASH0 region enough big to
contain StandaloneMM image(BL32).

This implements support for UEFI secure boot on SbsaQemu using
the standalone MM framework. This moves all of the software handling
of the UEFI authenticated variable store into the standalone MM
context residing in a secure partition.

Secure variable storage is located at 0x01000000 in secure NOR Flash.

Non-secure shared memory between UEFI and standalone MM
is allocated at the top of DRAM.
DRAM size of SbsaQemu varies depends on the QEMU parameter,
the non-secure shared memory base address is passed from
trusted-firmware through the device tree "/reserved-memory" node.

Together with "/reserved-memory" parsing implementation newly added
in this commit, pre-existing "/memory" node parsing is moved to
a helper function in FdtHelperLib.

+  Detailed build instructions can be found on the following link:
+  https://git.trustedfirmware.org/TF-A/trusted-firmware-a.git/tree/docs/plat/qemu-sbsa.rst
+
+  Then copy `bl1.bin` and `fip.bin` to the the edk2-non-osi directory:

+  Copy SBSA_FLASH0.fd and SBSA_FLASH1.fd to top $WORKSPACE directory.
+  Then extend the file size to match the machine flash size.

+  truncate -s 256M SBSA_FLASH[01].fd

+
+  To keep the UEFI variable storage after the succeeding build, use `dd` instead of `cp`.
+  ```
+  dd if=./Build/SbsaQemu/RELEASE_GCC5/FV/SBSA_FLASH0.fd of=./SBSA_FLASH0.fd conv=notrunc bs=2M count=8

 # Running
 
   The resulting SBSA_FLASH0.fd file will contain Secure flash0 image (TF-A code).
