igc: Use provided clock ID for history snapshot

Browse source

The PTP core indicates in system_device_crosststamp::clock_id the clock ID
for which the system time stamp should be taken. That allows to utilize
hardware timestamps with e.g. AUX clocks.

Save the provided clock ID and use it in igc_phc_get_syncdevicetime() for
taking the history snapshot.

No functional change.
