Add the new compatible "atmel,24mac402" to accommodate AT24MAC402.
The AT24MAC402 is a 2K Serial EEPROM and the 2-Kbit memory array
is internally organized as 16 pages of 16 bytes of EEPROM each.
The 48-bit EUI address in the AT24MAC402 are located in the extended
memory block.

Add the new compatible "microchip,24aa02e48" to accommodate 24AA02E48,
the 24AA02E48 is a 2K I2C Serial EEPROM with pre-programmed globally
unique, 48-bit node address, and 8-byte page size.

This patch implements the reading functionality for the generic I2C
EEPROM driver, which was just a non-functional stub until now.
Since the page size will be of importance for the writing support, we
add suitable members to the private data structure to keep track of it.
Compatibility strings for a range of at24c* chips are added.

There seem to be a few EEPROM drivers around - perhaps we should have a
single standard one? This simple driver is used for sandbox testing, but
could be pressed into more active service.
