RDMA/bnxt_re: Add support for MRs with Huge pages
Depending on the OS page-table configurations, applications
may request MRs which has page size alignment other than 4K
Underlying provider driver needs to adjust its PBL boundaries
according to the incoming page boundaries in the PA list.
Adding a capability to register MRs having pages-sizes other
than 4K (Hugepages).
