PS1: 
Why do you need to add this chip as a standalone entry? It's really similar to `MX25L12833F/MX25L12835F/MX25L12845E/MX25L12865E/MX25L12873F`, the only differences are:

1. Extra flag in `feature_bits`
2. Specified `reg_bits`
3. Specified `decode_range`

But quick research through these chips shows me that these changes can be applied to them as well. Does something go wrong when you use the entry I mentioned before?
