nand: Add SPL_NAND support to mxc_nand_spl
Add support for generic NAND SPL via the SPL framework into the mxc_nand_spl driver. This is basically just a simple rename and publication of the already implemented functions. To avoid the bare-bones functions getting in the way of the NAND_SPL, build them only if CONFIG_SPL_FRAMEWORK is not defined. Also make sure the requested payload is aligned to full pages, otherwise this simple driver fails to load the last page.
