Document the correct path to the split keyboard EEPROM files

[zvecr]

Description

This fixes incorrect paths to the split keyboard EEPROM files within the repo.

Other items for potential review:

• Should all references to eeprom files be updated to the full path ./quantum/split_common/eeprom-lefthand.eep and ./quantum/split_common/eeprom-righthand.eep?
• Should this PR update the location within ./keyboards/lets_split/keymaps/bbaserdem/README.md? Not required
• Should this PR remove the other eeprom files within minidox and deltasplit75 so that the only eeprom files are within the common folder? Not required

Travis CI error is unrelated.

Travis CI error is explicitly due to an issue with the avr-gcc compiler that it uses. I'm using the same version on both MSYS and ubuntu and it compiles under size....

Should all references to eeprom files be updated to the full path ./quantum/split_common/eeprom-lefthand.eep and ./quantum/split_common/eeprom-righthand.eep?

Yes, I think it should, honestly.

Should this PR update the location within ./keyboards/lets_split/keymaps/bbaserdem/README.md?

For keymap readme's, no. Just the main readme for the keyboard (and maybe the default keymap's readme".

Should this PR remove the other eeprom files within minidox and deltasplit75 so that the only eeprom files are within the common folder?

I'd say only if these keyboards have been converted and tested with the split common code. For now, it should be fine.

@drashna Thanks, i will make those updates shortly.

@bbaserdem Now that the Lets Split uses the split keyboard common code, there are stale reference to the eeprom files within ./keyboards/lets_split/keymaps/bbaserdem/README.md

Awesome, thanks!
