Documentation/cgroup-v1: fix outdated programming details
The cgroup-v1 documentation is out of date in a few places:
* cgroup controllers can no longer be compiled as modules since commit
3ed80a6 ("cgroup: drop module support"); the functions and fields
referenced here no longer exist.
* Controllers need to create of a cgroup_subsys object named
"<name>_cgrp_subsys" instead of "<name>_subsys" since commit
073219e ("cgroup: clean up cgroup_subsys names and initialization")
