This commit adds an _rcuidle suffix to a pair of trace events to
prevent the following splat:

===============================
[ INFO: suspicious RCU usage. ]
4.6.0-rc5-next-20160426+ #1114 Not tainted
-------------------------------
include/trace/events/clk.h:59 suspicious rcu_dereference_check() usage!

other info that might help us debug this:


RCU used illegally from idle CPU!
rcu_scheduler_active = 1, debug_locks = 0
RCU used illegally from extended quiescent state!
2 locks held by swapper/0/0:
 #0:  (&oh->hwmod_key#30){......}, at: [<c0121b40>] omap_hwmod_idle+0x18/0x44
