mambo: Make POWER9 look like DD2
In a recent Linux (next) change we added support for Radix Tree Size
(RTS) encodings for different POWER9 revs. Linux commit:

powerpc/mm/radix: Use different RTS encoding for different POWER9 revs
In mambo, we support the DD2 encoding of RTS but the PVR we advertise
is DD1. Hence Linux uses the wrong RTS encoding and we don't boot.
This fixes mambo to use the POWER9 DD2 PVR encoding.
