arm64: dts: rockchip: Fix EEPROM compatible on rk3399-nanopi-r4s-enterprise

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.
