staging: dgap: Merge dgap_fep5.h into dgap_driver.h
There is a lot of cleanup work to do on these digi drivers and merging as much as is possible will make it easier. I also notice that many merged drivers are single source and header. Signed-off-by: Mark Hounschell <markh@compro.net> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
