image_types_fsl.bbclass: Add U-Boot NAND support for i.MX23/i.MX28

This adds support to generate the U-Boot image for use with NAND
(uboot.mxsboot-nand) and allows for custom params to be given for
mxsboot using the MXSBOOT_NAND_ARGS variable which should be defined
in the machine definition file.
