    ramips: mt7621: use lzma-loader for ra21s & rg21s
    
    The rg21s fails to boot if the kernel is larger than about
    2,376 KiB. The ra21s is virtually identical hardware.
    Enabling lzma-loader resolves the issue on both the rg21s
    and ra21s (see FS#3057 on the issue tracker).
    
    Fixes: FS#3057
