cmdline: add reboot_timeout option

In case communication with KTF is not possible (no PS/2 keyboard nor UART port) add an option to automatically reboot after specified amount of time. The reboot_timeout by default is off. Value 0 means reboot immediately. Values unit is seconds. Please note a timer needs to be enabled for this functionality to work. Signed-off-by: Pawel Wieczorkiewicz <[email protected]>
