Both recipes (imx-boot and imx-mkimage) use the same source code
repository, so update both of them to the new NXP release, by copying
with minimal changes the recipes in meta-imx.
Also convert the original 'imx-mkimage' recipe, which was only for
native class, to a full target, native, nativesdk recipe. We need this
to be able to include the nativesdk one in our toolchain.
