fgraph: Change the name of cpuhp state to "fgraph:online"
[ Upstream commit a574e7f80e86c740e241c762923f50077b2c2a30 ]
The cpuhp state name given to cpuhp_setup_state() is "fgraph_idle_init"
which doesn't really conform to the names that are used for cpu hotplug
setups. Instead rename it to "fgraph:online" to be in line with other
states.
