Tomas Pilar 83683ddd3d plat/qemu: Use RNDR in stack protector 
When getting a stack protector canary value, check
if cpu supports FEAT_RNG and use that. Fallback to
old method of using a (hardcoded value ^ timer).

Radoslaw Biernacki 301d27d998 qemu: introducing sub-platforms to qemu platform 
This commit change the plat/qemu directory structure into:

`-- plat
    `-- qemu
        |-- common    (files shared with all qemu subplatforms)
        |-- qemu      (original qemu platform)
        |-- qemu_sbsa (new sqemu_sbsa platform)
        |-- subplat1
        `-- subplat2

This opens the possibility of adding new qemu sub-platforms which reuse
existing common platform code. The first platform which will leverage new
structure will be SBSA platform.
