sb/intel/common: Rename i2c_block_read() to i2c_eeprom_read()
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.
