netlink: specs: add genetlink-legacy spec for GTP
The GTP (GPRS Tunnelling Protocol, user plane) generic netlink family
has no YAML specification under Documentation/netlink/specs/, so it
cannot be consumed by the ynl tooling used for user-space clients,
documentation and selftests.
Add a genetlink-legacy spec describing the existing family: the PDP
context management commands (NEWPDP, DELPDP, GETPDP) and the GTP-U echo
request (ECHOREQ), the GTPA_* attribute set, and the "gtp" multicast
group. Command and attribute values are taken from
include/uapi/linux/gtp.h and match it one-to-one. The request
attributes of each command are the ones its handler in
drivers/net/gtp.c reads, and the reply attributes the ones
gtp_genl_fill_info() emits.
The notifications sent on the "gtp" group are not described: they reuse
the command values of the NEWPDP, DELPDP and ECHOREQ requests, which
the ynl code generator cannot express with the existing uapi header.
The family doc says so.
Add the matching CFLAGS_gtp entry to tools/net/ynl/Makefile.deps, so
the generated code is built against the tree's gtp.h instead of an
older one installed on the host.
This only adds the description; there is no kernel code or uapi change.
