    ramips: remove obsolete SPI flash nodes after kernel fix
    
    Remove incomplete SPI flash definitions from affected device tree files.
    These fragments only defined address-cells and size-cells without any
    actual flash configuration (partitions, compatible string, etc.).
    
    After applying openwrt/openwrt#20942 ("kernel: of: fix bad cell count error
    for SPI flash node"), the kernel properly handles SPI flash nodes without
    requiring these incomplete definitions in device-specific DTS files.
    
    This cleanup eliminates unnecessary code that was likely a workaround for
    the previous kernel issue.
