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.
