Bluetooth: add support for SIOCETHTOOL ETHTOOL_GET_TS_INFO
Bluetooth needs some way for user to get supported so_timestamping flags
for the different socket types.
Use SIOCETHTOOL API for this purpose. As hci_dev is not associated with
struct net_device, the existing implementation can't be reused, so we
add a small one here.
Add support (only) for ETHTOOL_GET_TS_INFO command. The API differs
slightly from netdev in that the result depends also on socket type.
