i40iw: Utilize physically mapped memory regions

Browse source

Add support to use physically mapped WQ's and MR's if determined
that the OS registered user-memory for the region is physically
contiguous. This feature will eliminate the need for unnecessarily
setting up and using PBL's when not required.
