wanrouter: delete now orphaned header content, files/drivers
The wanrouter support was identified earlier as unused for years, and so the previous commit totally decoupled it from the kernel, leaving the related wanrouter files present, but totally inert. Here we take the final step in that cleanup, by doing a wholesale removal of these files. The two step process is used so that the large deletion is decoupled from the git history of files that we still care about. The drivers deleted here all were dependent on the Kconfig setting CONFIG_WAN_ROUTER_DRIVERS. A stub wanrouter.h header (kernel & uapi) are left behind so that drivers/isdn/i4l/isdn_x25iface.c continues to compile, and so that we don't accidentally break userspace that expected these defines.

2* cycx_drv.c Cyclom 2X Support Module.
3*
4* This module is a library of common hardware specific
5* functions used by the Cyclades Cyclom 2X sync card.

17* ============================================================================
18* 1999/11/11 acme set_current_state(TASK_INTERRUPTIBLE), code
19* cleanup
20* 1999/11/08 acme init_cyc2x deleted, doing nothing
21* 1999/11/06 acme back to read[bw], write[bw] and memcpy_to and
22* fromio to use dpmbase ioremaped
23* 1999/10/26 acme use isa_read[bw], isa_write[bw] & isa_memcpy_to
24* & fromio
25* 1999/10/23 acme cleanup to only supports cyclom2x: all the other
26* boards are no longer manufactured by cyclades,
27* if someone wants to support them... be my guest!
28* 1999/05/28 acme cycx_intack & cycx_intde gone for good
29* 1999/05/18 acme lots of unlogged work, submitting to Linus...
30* 1999/01/03 acme more judicious use of data types
31* 1999/01/03 acme judicious use of data types :>
32* cycx_inten trying to reset pending interrupts
33* from cyclom 2x - I think this isn't the way to
34* go, but for now...
35* 1999/01/02 acme cycx_intack ok, I think there's nothing to do
36* to ack an int in cycx_drv.c, only handle it in
37* cyx_isr (or in the other protocols: cyp_isr,
38* cyf_isr, when they get implemented.
39* Dec 31, 1998 acme cycx_data_boot & cycx_code_boot fixed, crossing
40* fingers to see x25_configure in cycx_x25.c
41* work... :)
42* Dec 26, 1998 acme load implementation fixed, seems to work! :)
43* cycx_2x_dpmbase_options with all the possible
44* DPM addresses (20).
45* cycx_intr implemented (test this!)
46* general code cleanup
47* Dec 8, 1998 Ivan Passos Cyclom-2X firmware load implementation.
48* Aug 8, 1998 acme Initial version.
