cgroup, doc: make cgroup_disable doc more accurate
In doc, it said that 'Currently supported controllers - "memory"', but actually we can use cgroup_disable=cpu,cpuset and all other controllers, so this is confusing for cgroup users without much cgroup knowledge. We need to make it clear.

+ The effects of cgroup_disable=foo are:

+ a single hierarchy
+ - foo isn't visible as an individually mountable
