CPU_MIPS64 needs 8-byte alignment on the linker lists, otherwise an
exception may occur. Fixes an issue found on malta64 with QEMU:

 Breakpoint 1, lists_driver_lookup_name (name=0xffffffffbe043578 "root_driver") at /home/uboot/u-boot/drivers/core/lists.c:31
 31                      if (!strcmp(name, entry->name))
 [...]
 ld      a1,0(s0)

 (gdb) p/x &entry->name
 0xffffffffbe04b0d4
 (gdb) p/x $s0
 0xffffffffbe04b0d4

 $ grep __u_boot_list /tmp/malta64/u-boot.objdump
 4 __u_boot_list 000018e0  ffffffffbe04a4d4  ffffffffbe04a4d4  0004a584  2**2
