Uladzislau Rezki (Sony) 30b491e2b6 rcu-tasks: Move RCU-tasks initialization to before early_initcall()
[ Upstream commit 1b04fa9900263b4e217ca2509fd778b32c2b4eb2 ]

PowerPC testing encountered boot failures due to RCU Tasks not being
fully initialized until core_initcall() time.  This commit therefore
initializes RCU Tasks (along with Rude RCU and RCU Tasks Trace) just
before early_initcall() time, thus allowing waiting on RCU Tasks grace
periods from early_initcall() handlers.
