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.
