[ Upstream commit e2f4b3be1d3c73176db734565b160250cc1300dd ]
For MIPS pre-boot, when CONFIG_KERNEL_ZSTD=y, the decompressor function uses __bswapdi2(), so this object file should be added to the target object file.
Fixes these build errors:
mips-linux-ld: arch/mips/boot/compressed/decompress.o: in function `xxh64': decompress.c:(.text+0x8be0): undefined reference to `__bswapdi2' mips-linux-ld: decompress.c:(.text+0x8c78): undefined reference to `__bswapdi2' mips-linux-ld: decompress.c:(.text+0x8d04): undefined reference to `__bswapdi2' mips-linux-ld: arch/mips/boot/compressed/decompress.o:decompress.c:(.text+0xa010): more undefined references to `__bswapdi2' follow
