2020-03-17src (minus soc and mainboard): Remove copyright noticesPatrick Georgi
They're listed in AUTHORS and often incorrect anyway, for example: - What's a "Copyright $year-present"? - Which incarnation of Google (Inc, LLC, ...) is the current copyright holder? - People sometimes have their editor auto-add themselves to files even though they only deleted stuff - Or they let the editor automatically update the copyright year, because why not? - Who is the copyright holder "The coreboot project Authors"? - Or "Generated Code"? Sidestep all these issues by simply not putting these notices in individual files, let's list all copyright holders in AUTHORS instead and use the git history to deal with the rest.

Datasheets describe the used command as 'I2C Read' but adding the word 'eeprom' in between should avoid further confusion with other block commands. Followups will add a symmetrical pair of commands i2c_block_read() and i2c_block_write() that operate via I2C_EN bit and have a 32 byte size restriction on block transfers. For some hardware revision these block commands are available, while 'I2C Read' was not.
