    ipq40xx: revert Cell-C RTL30VW to legacy caldata extraction
    
    This partially reverts
    commit cfc13c44595d ("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 at X nodes in
    working system:
    
    root at OpenWrt:~# echo $(cat /sys/firmware/devicetree/base/soc/spi at 78b5000/flash at 0/partitions/partition at 170000/label)
    0:ART
    root at OpenWrt:~# ls /sys/firmware/devicetree/base/soc/spi at 78b5000/flash at 0/partitions/partition at 170000/
    label  name   reg
    
    Revert to legacy method fixed the problem.
