cpuidle,arch: Mark all regular cpuidle_state::enter methods __cpuidle

For all cpuidle drivers that do not use CPUIDLE_FLAG_RCU_IDLE (iow,
the simple ones) make sure all the functions are marked __cpuidle.

( due to lack of noinstr validation on these platforms it is entirely
  possible this isn't complete )
