Move PD allocation and deallocation from firmware to driver. At
driver load time all the PDs will be requested from firmware and their
management will be handled by driver to reduce mailbox commands
overhead at runtime.

This patch implements routine to query the PFC priority from the
adapter port.
Following are the changes implemented:
* A new FW command is implemented to query the operational/admin DCBX
configuration from the FW and obtain active priority(service
level).
* Adds support for the async event reported by FW when the PFC
priority changes. Service level is re-initialized during modify_qp
or create_ah, based on this event.
* Maintain SL value in ocrdma_dev structure and refer that as and
when needed.

1) Increase STAG Array size.
2) Max inline data size should be set to the same value
used during QP creation
3) Set max_sge_rd to zero since we dont support RD transport in our adapters.
4) Max cqes reported in ibv_devinfo should be from QUERY_CONFIG.

Create_CQ verb doesn't provide a PD pointer. So, until now we are
creating all (both userspace and kernel) CQ DB regions from PD0. This
will result in mmapping PD0 to applications. A rogue userspace
application can mess things up.
Also more serious issues is even the be2net NIC uses PD0.
This patch addresses this problem by:
1) Create a PD page for every userspace application when the
alloc_ucontext is called. This will be destroyed in
dealloc_ucontext.
2) All CQs for that context will use the PD allocated in ucontext.
3) The first create_PD call from application will result in returning
the PD address from its ucontext (no new PD will be created).
4) For subsecquent create_pd calls from application, we create new PDs for
the application.
