netlink: specs: devlink: add the remaining command to generate comple…

…te split_ops

Currently, some of the commands are not described in devlink yaml file
and are manually filled in net/devlink/netlink.c in small_ops. To make
all part of split_ops, add definitions of the rest of the commands
alongside with needed attributes and enums.

Note that this focuses on the kernel side. The requests are fully
described in order to generate split_op alongside with policies.
Follow-up will describe the replies in order to make the userspace
helpers complete.
