RDMA/hns: Configure capacity of hns device
This patch adds new device capability for IB_DEVICE_MEM_MGT_EXTENSIONS to
indicate device support for the following features:
1. Fast register memory region.
2. send with remote invalidate by frmr
3. local invalidate memory regsion
As well as adds the max depth of frmr page list len.
