Updates for https://www.rockbox.org/wiki/SonyNWDestTool - 2 more working

[Gruntbug]

I just used SonyNWDestTool on two players that aren't listed to change them to English (from Japanese). I was going to see if I could edit the wiki myself but it looks like that's not allowed.  Can anyone add these two to the list?

• Sony Walkman NW-S14
• Sony Walkman NW-S764

Both worked with no issues. I can take screenshots or whatever is needed to prove it.

I also have a Sony Walkman NW-S775 which didn't work. Here is the output:
