target/sparc: sun4u Invert Endian TTE bit

Browse source 
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 =)
