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.
