NanoPi R4S has a EEPROM attached to the 2nd I2C bus (U92), which
stores the MAC address.
FriendlyElec ship two versions of the R4S [1]: The standard as well
as the enterprise edition with only the enterprise edition including
the EEPROM chip that stores the unique MAC address.
1. https://wiki.friendlyelec.com/wiki/index.php/NanoPi_R4S#Differences_Between_R4S_Standard_Version_.26_R4S_Enterprise_Version
Changes in v4:
- Removed `mac-address` cell as it breaks the standard edition
Changes in v3:
- Added address-cells and size-cells
Changes in v2:
- Added the size of EEPROM
- Added `mac-address` cell to pass the MAC address to kernel
- Removed `read-only` property in EEPROM node

This needs to go differently.
If the eeprom is only preset on the enterprise-version, you need
a separate devicetree for it, that provides the eeprom node.
Declaring the eeprom "in error" on a device that doesn't have it,
isn't the way to go.
Look for example at rockchip/rk3399-nanopi-m4b.dts for reference
on how to do it - and also remember to add the new binding
for that board. And can also again declare the correct mac-address
cell.

NanoPi R4S has a EEPROM attached to the 2nd I2C bus (U92), which
stores the MAC address.
Changes in v4:
- Fixed typo error: `nvmem-cells-names` -> `nvmem-cell-names`
Changes in v3:
- Added address-cells and size-cells
Changes in v2:
- Added the size of EEPROM
- Added `mac-address` cell to pass the MAC address to kernel
- Removed `read-only` property in EEPROM node
