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.
