IB/mlx5: Device memory support in mlx5_ib
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.
