'A53_CORE' is just a mux and no need to be critical, being critical will cause its parent clock always ON which does NOT make sense, to make sure CPU's hardware clock source NOT being disabled during clock tree setup, need to move the 'A53_SRC'/'A53_CORE' reparent operations to after critical clock 'ARM_CLK' setup finished.
