Tested with OpenBSD on sun4u. Solaris 10 is my actual goal, but unfortunately a
separate keyboard issue remains in the way.

This bit configures endianness of PCI MMIO devices. It is used by
Solaris and OpenBSD sunhme drivers.
Tested working on OpenBSD.
Unfortunately Solaris 10 had a unrelated keyboard issue blocking
testing... another inch towards Solaris 10 on SPARC64 =)

Notice new attribute, byte swap, and force the transaction through the
memory slow path.
Required by architectures that can invert endianness of memory
transaction, e.g. SPARC64 has the Invert Endian TTE bit.
