There are no BATS on BookE - we have the TLBCAM instead.  Also correct
the page size information to included extended (1G and 4G) sizes.

Lame, I know, but this drives me batty every time I see it, and I've had
customers get confused because of it.  I've finally gotten irritated enough
to send a patch.
