fsl-layerscape: Move GIC RD tables init to soc.c

Move GIC redistributor tables initialization to CPU setup function.

This patch introduces a GIC redistributor tables init function, and
moves the function of reserving memory for GIC redistributor tables
to soc.c and adds a argument for the memory size to reserve, BTW
rename the function so that it is more readable.
