Looks good and like the right thing to me.

To check I understand how the QOM stuff is working here,
for a transaction master we expose an MR link property,
which the board sets to be a pointer to some appropriate
MR (which is owned by the board).
Conversely, for a transaction slave (ie a device), the
device owns its own memory regions. The board can map
those via the traditional APIs for putting MRs in
containers, or it could choose to set the MR 'container'
link property to point at the container MR (plus the
addr property).

The transaction master properties/API actually make
much more sense to me than the slave ones...
