The jsm driver doesn't currently use the uart_handle_*_change helper functions, which are the obvious place for things like linuxpps to tie into (which it now does of course), and as a result the jsm driver can not be used with linuxpps and anything else that ties into the serial_core helper functions. This patch adds calls to these helper functions whenever the value they manage changes. That actual storage of the state is not modified since the jsm driver caches the current settings (The 8250 driver reads them everytime a user asks for the state), and only updates them whenever they change.
