Reordering the current entries is not needed, but if you do it then you
must mention it in the commit message above.

Also make sure to not change any formatting; checkpatch is now
complaining about whitespace issues (always run checkpatch before
submitting).

Use two structs for this: zte_me3620_blacklist and zm8620_xl_blacklist
even if they reserve the same ports.

If really want to reorder the current entries, then at least make sure
the end result is indeed sorted.
