Krzysztof Halasa <khc@pm.waw.pl> who is the author of drivers/net/wan/wanxl
(CCed) noted that "This is a driver for an old obscure early PCI 2 Mbit/s 
WAN board" so the probability of getting this migrated to the firmware 
interface is quite low.

Not sure if this form of addressing it is accpetable, it simply adds
a 4th case for the .inc_shipped with a INFO message noting it as
deprecated. 

proposed alternative for 2/3 below.

limit _shipped to c,h and S files

_shipped targets are intended for generated source files which should
not permit .o binary blobs which is currently the case. This patch
simply restricts _shipped targets to .c, .h and .S files.

Note that limiting it to .c, .h and .S only would breaks the handling
of drivers/net/wan/wanxlfw.inc_shipped which is named .inc for mainly
historic reasons as a work around the .inc_shipped is treated as
expected but an additional note is printed indicating that this is
deprecated.

  INFO: use of .inc_shipped files is deprecated
  SHIPPED drivers/net/wan/wanxlfw.inc

This patch is against Linux 3.17.0-rc7
