phy: mscc: Fix when PTP clock is register and unregister

Browse source

[ Upstream commit 882e57cbc7 ]

It looks like that every time when the interface was set down and up the
driver was creating a new ptp clock. On top of this the function
ptp_clock_unregister was never called.
Therefore fix this by calling ptp_clock_register and initialize the
mii_ts struct inside the probe function and call ptp_clock_unregister when
driver is removed.
