stmmac: intel: Enable correction of MAC propagation delay
All captured timestamps should be corrected by PHY, MAC and CDC introduced latency/errors. The CDC correction is already used. Enable MAC propagation delay correction as well which is available since commit 26cfb838aa00 ("net: stmmac: correct MAC propagation delay"). Before: |ptp4l[390.458]: rms 7 max 21 freq +177 +/- 14 delay 357 +/- 1 After: |ptp4l[620.012]: rms 7 max 20 freq +195 +/- 14 delay 345 +/- 1 Tested on Intel Elkhart Lake.
