v8: - use gpio 0 and 1, align dtb with kernel gpio-restart, gpio-poweroff,
       change define names, trigger on upper front. (Peter Maydell).
 v7: - same as v6, but resplit patches: patch 2 no function changes and refactor
	gpio setup for virt platfrom and patch 3 adds secure gpio.
 v6: - 64k align gpio memory region (Andrew Jones)
     - adjusted memory region to map this address in the corresponding atf patch
 v5: - removed vms flag, added fdt  (Andrew Jones)
     - added patch3 to combine secure and non secure pl061. It has to be
       more easy to review if this changes are in the separate patch.
 v4: rework patches accodring to Peter Maydells comments:
	- split patches on gpio-pwr driver and arm-virt integration.
	- start secure gpio only from virt-6.0.
	- rework qemu interface for gpio-pwr to use 2 named gpio.
	- put secure gpio to secure name space.
 v3: added missed include qemu/log.h for qemu_log(.. 
 v2: replace printf with qemu_log (Philippe Mathieu-Daudé)

This patch works together with ATF patch:
