Use dm_i2c_probe() rather than i2c_get_chip() when trying to access
board-detection EEPROM devices. This has the advantage of more gracefully
handling the case when the EEPROM is not present by allowing to exit the
function early rather than failing and outputting an error message on the
I2C transactions that follow.
