busybox: remove libdigi dependency

The flash_eraseall busybox utility is not used in the ccimx6 and ccimx6ul
platforms. Its corresponding patch (and the library it depends on) can be
removed from the busybox recipe.

-flash_eraseall: disable JFFS2 clean markers for some platforms
-
-Some platforms (i.MX5X, CPX2) require atomic access to OOB otherwise
-the JFFS2 information in the OOB leads to errors when mounting the
-file system.
-
-For these platforms, disable the possibility of writing JFFS2 clean
-markers when erasing the flash.
