ath79: move lzma-loader to the end of available RAM
In certain cases, the uncompressed initramfs image will overwrite the lzma-loader, which is currently only 10 MB away from kernel image start. To prevent this, change LZMA_TEXT_START to 24 MB, so loader and compressed image have 8 MB at the end of RAM and uncompressed image has 24 MB available. This is only enabled for ath79 at the moment, as there we can be sure that all devices have 32+ MB RAM and TARGET_INITRAMFS_COMPRESSION_LZMA is not enabled there. Despite, since lzma-loader is currently build specifically for ath79 anyway, there is no need to re-specify LOADADDR and LZMA_TEXT_START in image/Makefile, so the values are set directly in image/lzma-loader/Makefile and the overwrite in image/Makefile is removed.
