This patch adds the MR datastructures based on hfi1 into rvt. For now the
data structures are defined in include/rdma/rdma_vt.h but once all MR
functionality has been moved from the drivers into rvt these should move to
rdmavt/mr.h

The pkey table will reside in the rvt structure but it will be modified
only when the driver requests then rvt will simply read the value to return
in the query.

Instead of trying to handle each parameter separately, add ib_device_attr
to rvt_driver_params. This means drivers will fill this in and pass to the
rvt registration function.

This patch introduces the basics for a new module called rdma_vt. This new
driver is a software implementation of the InfiniBand verbs and aims to
replace the multiple implementations that exist and duplicate each others'
code.
While the call to actually register the device with the IB core happens in
rdma_vt, most of the work is still done in the drivers themselves. This
will be changing in a follow on patch this is just laying the groundwork
for this infrastructure.
