eeprom: Add support for 24c1025 EEPROM
This is the Microchip version of the Atmel 24c1024, which is already
supported. The key difference between them is that the I2C address
bit used to select between the two banks is bit 2 for the 1025 and not
bit 0 as in the 1024.
Add a flag to describe this difference.
