[PATCH net v2 2/5] net: dsa: b53: do not enable RGMII delay on bcm63xx

[Jonas Gorski]

bcm63xx's RGMII ports are always in MAC mode, never in PHY mode, so we
shouldn't enable any delays and let the PHY handle any delays as
necessary.

This fixes using RGMII ports with normal PHYs like BCM54612E, which will
handle the delay in the PHY.

Fixes: ce3bf94871f7 ("net: dsa: b53: add support for BCM63xx RGMIIs")
