eeprom: at24: Add support for Microchip 24AA025E48/24AA025E64 EEPROMs 



Add "microchip,24aa025e48", "microchip,24aa025e64" compatible for the
usage w/ 24AA025E{48, 64} type of EEPROMs where "24aa025e48" stands
for EUI-48 address and "24aa025e64" stands for EUI-64 address.

[andrei.simion@microchip.com: Use AT24_DATA_CHIP with AT24_FLAG_READONLY for
24AA025E{48, 64} type of EEPROMs. Reword commit message.]
