Hou Zhiqiang 341238fd13 arm: fsl-layerscape: move forward the non-secure access permission setup
Move forward the basic non-secure access enable operation, so the
subsequent individual device access permission can override it.
And collect the dispersed callers in board level, and then move
them to SoC level.
