IB/mlx5: Extend UAR stuff to support dynamic allocation
This patch extends the alloc context flow to be prepared for working with dynamic UAR allocations. Currently upon alloc context there is some fix size of UARs that are allocated (named 'static allocation') and there is no option to user application to ask for more or control which UAR will be used by which QP. In this patch the driver prepares its data structures to manage both the static and the dynamic allocations and let the user driver knows about the max value of dynamic blue-flame registers that are allowed. Downstream patches from this series will enable the dynamic allocation and the association as part of QP creation.
