igc: fix build errors for PTP
[ Upstream commit 87758511075ec961486fe78d7548dd709b524433 ]
When IGC=y and PTP_1588_CLOCK=m, the ptp_*() interface family is
not available to the igc driver. Make this driver depend on
PTP_1588_CLOCK_OPTIONAL so that it will build without errors.
Various igc commits have used ptp_*() functions without checking
that PTP_1588_CLOCK is enabled. Fix all of these here.
Fixes these build errors:
