qemu: Add support for stack canary protection
Allow qemu users to enable stack protection. Since the virt platform does not provide an RNG, use a basic, timer-based, canary generation, similarly to FVP. Increase SRAM size and BL2 size to fit images when stack protection is enabled. Notice that stack protection is not enabled by default in qemu. Fixes ARM-software/tf-issues#568 Signed-off-by: Michalis Pappas <mpappas@fastmail.fm>
