This partially reverts
commit cfc13c4459 ("ipq40xx: utilize nvmem-cells for macs & (pre-)calibration data").

After switching to nvmem RTL30VW, wifi was broken:

Bootloader mangles in NAND partitions and removes precal@X nodes in
working system:

root@OpenWrt:~# echo $(cat /sys/firmware/devicetree/base/soc/spi@78b5000/flash@0/partitions/partition@170000/label)
0:ART
root@OpenWrt:~# ls /sys/firmware/devicetree/base/soc/spi@78b5000/flash@0/partitions/partition@170000/
label  name   reg

Revert to legacy method fixed the problem.
