Rework each affected mtdsplit driver to make use of -ENOENT error
instead of -ENODEV to handle new kernel that checks error from parser on
subpartitions.
The only acceptable error is -ENOENT that skip the parser. This follow
pattern used upstream and also by an mtdsplit parser, mtdsplit_bcm_wfi,
and also by a workaround currently implemented for mtdsplit_mstc_boot.
