    lantiq: fritz7362sl: add partition subnode for SPI flash
    
    Without a partition subnode ofpart_core still parses direct subnodes as
    partitions, but it ignores nodes with a compatible property. Due to
    this, the switch to nvmem-cells made the urlader partition inaccessible.
    As a result, the wireless network was broken, as the calibration data
    is read from that partition by a script.
    
    Fixes: #8983
