Current QEMU doesn't reset PL061 device state. As a result the device keeps a stale state after guest reboots. This causes VM fail to recceive GPIO commands (e.g. virsh shutdown/reoot commands) after reboot. This patchset adds reset support for PL061 devices. The second patch removes an unused field.
V3: * hook up dc->reset to existing reset function. And stop calling reset in initfn() * add Reviewed-by V2: * derived from V1 after further debug. Now it resets device state instead of using pulse for GPIO IRQ.
