[PATCH 4/6] cpuidle: psci: Drop redundant assignment of CPUIDLE_FLAG_RCU_IDLE

When using the hierarchical topology and PSCI OSI-mode we may end up
overriding the deepest idle-state's ->enter|enter_s2idle() callbacks, but
there is no point to also re-assign the CPUIDLE_FLAG_RCU_IDLE for the
idle-state in question, as that has already been set when parsing the
states from DT. See init_state_node().
