When using DevX API, memory for door-bell records should be allocated by PMD and registered using DevX API. This patch implements the utility functions to support it: - Add struct mlx5_devx_dbr_page, containing door-bells page data. - Add list of struct mlx5_devx_dbr_page door-bell pages to device private data. - Implement function mlx5_alloc_dbr_page() to allocate page for door-bell records, and register it using DevX API. - Implement function mlx5_get_dbr(). to acquire a door-bell record from the door-bells page, allocating a new page if needed. - Implement function mlx5_release_dbr() to release a door-bell record that is no longer needed, freeing the containing page if it becomes empty.
