[Intel-wired-lan] [PATCH next] igc: make non-global functions static

[Chen Zhou]

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?
