mpc85xx: change legacy "eeprom" compatible
silences the following message: > eeprom 0-0051: eeprom driver is deprecated, please use at24 instead The chip was likely a Dallas Semiconductor and later MAXIM part before Analog Devices, Inc. bought MAXIM. From the datasheet: "The DS28CN01 combines 1024 bits of EEPROM with challenge-and-response authentication security implemented with the FIPS 180-1/180-2 and ISO/IEC 10118-3 Secure Hash Algorithm (SHA-1)." ... "Write Access Requires Knowledge of the Secret and the Capability of Computing and Transmitting a 160-Bit MAC as Authorization" OpenWrt doesn't use it. There's no in-kernel driver from what I know. Let's document that the chip is at the location. Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
