MIPS: boot/compressed/: add __bswapdi2() to target for ZSTD decompression 

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

Fixes: 0652035a57 ("asm-generic: unaligned: remove byteshift helpers")
Fixes: cddc40f561 ("mips: always link byteswap helpers into decompressor")
