mainboard/emulation/qemu-sbsa: Add qemu-sbsa board

Browse Source 
Add coreboot support for qemu's sbsa-ref (Server Base System
Architecture) machine (-m sbsa-ref).

The qemu-sbsa coreboot port runs on EL2 and is the payload of the
EL3 firmware (Arm Trusted Firmware).

Note that, coreboot expects a pointer to the FDT in x0. Make sure
to configure TF-A to handoff the FDT pointer.

Example qemu commandline:

  qemu-system-aarch64 -nographic -m 2048 -M sbsa-ref \
                      -pflash <path/to/TFA.fd> \
                      -pflash <path/to/coreboot.rom>
