The GENET controller on the Raspberry Pi 4 (2711) is typically
interfaced with an external Broadcom PHY via a RGMII electrical
interface. To make sure that delays are properly configured at the PHY
side, ensure that we get a chance to have the dedicated Broadcom PHY
driver (CONFIG_BROADCOM_PHY) enabled for this to happen.

when not needed")

David,

I would like Marek to indicate whether he is okay or not with this
change. Thanks!
