igc: Enable internal i225 PPS
The i225 device can produce one interrupt on the full second, much
like i210 - from where this patch is inspired.
This patch sets up the full second interruption on the i225 and when
receiving it, it sends a PPS event to PTP (Precision Time Protocol)
kernel subsystem.
The PTP subsystem exposes the PPS events via ioctl and sysfs, and one
can use the `testptp` tool (tools/testing/selftests/ptp) to check that
the events are being generated.
