ramips: adjust LZMA_TEXT_START for 32MB RAM devices

Currently the lzma-loader is placed in RAM at 32MB offset, which does not
make sense for devices with only 32MB RAM. If we adjust LZMA_TEXT_START to
24MB offset, then the lzma-loader can be used on those devices and still
about 24MB memory will be available for uncompressed image, which should be
enough for most use cases.
