This patch adds the mlx5_ib driver implementation for the device memory allocation API. It implements the ib_device callbacks for allocation and deallocation operations as well as a new mmap command support which allows mapping an allocated device memory to a VMA. The change also adds reporting of device memory maximum size and alignment parameters reported in device capabilities. The allocation/deallocation operations are using new firmware commands to allocate MEMIC memory on the device.
