    ath79: lzma-loader: expose LZMA_TEXT_ADDRESS configuration again
    
    initramfs for some devices grew so big, that it can't be loaded within
    the previous 32MB RAM limit. Make the LZMA_TEXT_ADDRESS configurable
    per-target once again, to fix it for bigger devices, while maintaining
    compatibility with previous ones.
