ARM: 7700/2: Make cpu_init() notrace
On resume from CPU power down any trace hooks enabled in cpu_init()
will get called before that function has done set_my_cpu_offset(),
so any use of per-cpu variables by trace hook code will cause bad
things to happen. Prevent this by marking the function notrace.
This fixes lockups/crashes seen when enabling function tracer on TC2
with the not yet mainlined cpuidle driver.
