    ramips: use default lzma dictionary size for better performance
    
    limit dictionary size patch was introduced to solve the well known
    "LZMA ERROR 1 - must RESET board to recover" error.
    09b6755946409d8fd8 "ramips: limit dictionary size for lzma compression"
    
    It seems that it has failed recently and we can use lzma loader to fix
    this error by adding "$(Device/uimage-lzma-loader)". So just remove it
    to use the default parameter -d24 for a higher compression ratio.
