[ Upstream commit 4af523551d876ab8b8057d1e5303a860fd736fcb ]
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.
