Embargo on I2C API and drivers

Dear RIOTers,

As of today start the embargo regarding I2C. All PR’s related to I2C device or CPU drivers, new I2C board support etc. will be postponed for up to 2 weeks.

A dedicated branch has been created (new_i2c_if) based on the lastest master.

If you’re willing to participate, don’t hesitate :slight_smile: There is a synchronization effort on this issue #6577 (the complete list is now up-to-date).

Cheers !
