Introduce driver specific uapi functionalites. Added a alloc_page functionality for user library to allocate specific pages. Currently added support for allocating write combine pages for push functinality. This interface shall be extended for other page allocations. Allocate a WC page using the uapi hook for enabling the low latency push in Gen P5 adapters for small packets. This is supported only for the user space QPs.
