In order to more successfully script with ntb_tool it's useful to have a link file to check the link status so that the script doesn't use the other files until the link is up. This commit adds a 'link' file to the debugfs directory which reads boolean (Y or N) depending on the link status. Writing to the file change the link state using ntb_link_enable or ntb_link_disable. A 'link_event' file is also provided so an application can block until the link changes to the desired state. If the user writes a 1, it will block until the link is up. If the user writes a 0, it will block until the link is down.
