igb: Correct PTP support query from ethtool.
Update ethtool_get_ts_info to not report any supported functionality on
82575 and add support for V2 Sync and V2 Delay packets. In the case
where CONFIG_IGB_PTP is not defined, we should be reporting default
values.
v2: Correct the function to return EOPNOTSUPP when there is no PTP support
or the device does not support PTP. Also fix minor whitespace issue.
