batman-adv: Drop documentation about debugfs files
The debugfs files were marked as deprecated by commit 00caf6a2b318
("batman-adv: Mark debugfs functionality as deprecated"). The documentation
should not advertise its usage anymore and instead promote the generic
netlink family and a userspace tool to access it.
