Maxim Uvarov ffb07b0438 plat/qemu: trigger reboot with secure pl061 
Secure pl061 qemu driver allows to rize the GPIO pin
from the secure world to reboot and power down
virtual machine.

Do not define secure-gpio for sbsa-ref platform due to
reboot is done via sbsa-ec watchdog.

Andrew Walbran 61cbd41d79 qemu: Implement qemu_system_off via semihosting. 
This makes the PSCI SYSTEM_OFF call work on QEMU. It assumes that QEMU has
semihosting enabled, but that is already assumed by the image loader.

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.
