[][kernel][mt7988][eth][mediatek-ge-soc: Fix VCM K failure]

[Description]
Fix VCM K failure:
1. Disable TX power saving first, so that TX-VCM calibration can go on.
2. We don't calibrate Gphy twice. Remove calibration part in config_init().
Now, calibration will only take place at probe().
3. Print VCM calibration final result even it's successful.

Without this patch, TX-VCM won't work correctly on MT7988
