power: reset: Add QEMU virt-ctrl driver Add a new driver for the 'virt-ctrl' device found on QEMU virt machines (e.g. m68k). This device provides a simple interface for system reset and power off [1]. This driver utilizes the modern system-off API to register callbacks for both system restart and power off. It also registers a reboot notifier to catch SYS_HALT events, ensuring that LINUX_REBOOT_CMD_HALT is properly handled. It is designed to be generic and can be reused by other architectures utilizing this QEMU device.

power: Drop unused assignment of platform_device_id driver data The driver explicitly set the .driver_data member of struct platform_device_id to zero without relying on that value. Drop this unused assignments. While touching this array unify spacing, use a named initializer for .name and drop trailing commas after the list terminators.
