Subject: [PATCH net-next v2] tg3: move init/deinit from open/close to probe/remove

Move init and deinit of PTP support from open/close functions
to probe/remove funcs to avoid removing/re-adding of associated PTP
device(s) during ifup/ifdown.

v2: tg3_ptp_init call moved to correct place (thx. Prashant)
