igc: make non-global functions static
Fix sparse warning: drivers/net/ethernet/intel/igc/igc_ptp.c:512:6: warning: symbol 'igc_ptp_tx_work' was not declared. Should it be static? drivers/net/ethernet/intel/igc/igc_ptp.c:644:6: warning: symbol 'igc_ptp_suspend' was not declared. Should it be static?
