3ae331c751 RDMA/irdma: Add QoS definitions 
Add definitions for managing the RDMA HW work scheduler (WS) tree.

A WS node is created via a control QP operation with the bandwidth
allocation, arbitration scheme, and traffic class of the QP specified.
The Qset handle returned associates the QoS parameters for the QP.
The Qset is registered with the LAN and an equivalent node is created
in the LAN packet scheduler tree.

d1850c005a RDMA/irdma: Add HMC backing store setup functions 
HW uses host memory as a backing store for a number of
protocol context objects and queue state tracking.
The Host Memory Cache (HMC) is a component responsible for
managing these objects stored in host memory.

Add the functions and data structures to manage the allocation
of backing pages used by the HMC for the various objects
