This implements support for UEFI secure variable storage
using standalone MM framework on qemu_sbsa platform.

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

Increase SHARED_RAM_SIZE in sbsa_qemu platform from 4KB to 8KB.

sbsa_qemu uses SHARED_RAM for mail box and hold state of each cpus. If
qemu is configured with 512 cpus, region size used by qemu is greater
than 4KB.

This patch adds mapping for secure FLASH0 for qemu/virt and
qemu/qemu_sbsa platforms. This change is targeted for sbsa but since both
platforms share common code, changes in common defines was necessary.

For qemu_sbsa, this patch adds necessary mapping in order to boot without
semi-hosting from secure FLASH0. EFI need to stay in FLASH1 (share it with
variables) since it need to "run in place" in non secure domain. Changes
for this are under RFC at edk2-platforms mailing list:
https://patches.linaro.org/patch/171327/


(edk2-platforms/Platform/Qemu/SbsaQemu/SbsaQemu.dsc).

In docs qemu/virt is described as using semi-hosting, therefore this change
should be orthogonal to existing assumptions while giving possibility to
store both bl1 and fip in FLASH0 at some point (additional changes required
for that).

This patch introduces Qemu SBSA platform.
Both platform specific files where copied from qemu/qemu with changes for
DRAM base above 32bit and removal of ARMv7 conditional defines/code.
Documentation is aligned to rest of SBSA patches along the series and
planed changes in edk2-platform repo.

Fixes ARM-software/tf-issues#602
