igb: refactor igb_ptp_adjfine_82580 to use diff_by_scaled_ppm

Browse source

Driver's .adjfine interface functions use adjust_by_scaled_ppm and
diff_by_scaled_ppm introduced in commit 1060707e38
("ptp: introduce helpers to adjust by scaled parts per million")
to calculate the required adjustment in a concise manner,
but not igb_ptp_adjfine_82580.
Fix it by introducing IGB_82580_BASE_PERIOD and changing function logic
to use diff_by_scaled_ppm.
