PATCH 1/1 arm64: dts: rockchip: rk3399-nanopi-r4s-enterprise: Fix EEPROM compatible
The EEPROM used on the R4S (enterprise) is the 24AA025E48T-I/OT from MicroChip. This is a 2-Kbit EEPROM with 16-byte page size. The latter half of the EEPROM is read-only, and the last 48 bits contain a globally unique MAC address. That is to say this is not an ordinary EEPROM.
The compatible for this type of EEPROM was introduced later that the board. Switch over to the correct compatible now that it is available.

This should probably not be backported without the matching changes to the DT binding and the at24 driver.
