[U-Boot] [PATCH v2] tools: moveconfig: cleanup whitelist entries

[Chris Packham]

After moving to KConfig and removing from all headers options should be
removed from config_whitelist.txt so the build starts complaining if
someone adds them back.

Simon asked for it so here you go. I also thought about cleaning up the
README file references too but that will take a little bit of work to
parse reliably.

Changes in v2:
- Correct typo
- Collect act from Masahiro
