net/mlx5e: Handle IPsec offload for RX datapath in switchdev mode
Reuse tun opts bits in reg c1, to pass IPsec obj id to datapath.
As this is only for RX SA and there are only 11 bits, xarray is used
to map IPsec obj id to an index, which is between 1 and 0x7ff, and
replace obj id to write to reg c1.
