driver/fsl_ifc: Add a function to finalize CS0 address binding

For fsl-lsch3 NOR flash boot, IFC CS0 needs to be binded with address within 32-bit at fist. After u-boot relocates to DDR, CS0 can be binded to higher address to support large space. Signed-off-by: York Sun <yorksun@freescale.com> CC: Prabhakar Kushwaha <prabhakar@freescale.com>
