ramips: soc wmac eeprom cleanup

Move eeprom extraction from scripts to dts files.
Additionally there are few other changes like:
- whitespace fixes
- add partition labels where needed
- BR6524N board doesn't exist (lost in translation?)
- fix Edimax 3g-6200nl model
- add wmac eeprom to dts for Asus RT-N14U board

Compile tested all subtargets and their profiles.
Run tested on:
- Asus RT-N15
- Asus RT-N14U
- Buffalo WHR-600D
- Argus ATP52B
- Sparklan WCR-150GN

Few problems noted:
- many boards didn't have wmac eeprom information defined at all
- several boards don't have any patitions defined (see FIXME comments in dts)
