Remove mips MD atomic_load_64 and atomic_store_64.

The only users of the functions were db_read_bytes() and
db_write_bytes() ddb(4) interfaces.  Replace the calls with direct
reads and writes, which are automatically atomic on 64bits and n32.

Note that removed assembler implementation for mips32 is not atomic
anyway.
