2021-07-02hw/gpio/gpio_pwr: use shutdown function for rebootMaxim Uvarov1-1/+1

2021-01-29hw: gpio: implement gpio-pwr driver for qemu reset/poweroffMaxim Uvarov1-0/+70
Implement gpio-pwr driver to allow reboot and poweroff machine. This is simple driver with just 2 gpios lines. Current use case is to reboot and poweroff virt machine in secure mode. Secure pl066 gpio chip is needed for that.
