[U-Boot] [PATCH v2] net: macb: Fix GMAC not work when enable DM_ETH

[Wenyou Yang]

Always search the PHY to determine the macb->phy_addr before using
the PHY to fix "No PHY present" error.

Fix the wrong test of the GMAC's phy interface mode, it should be
PHY_INTERFACE_MODE_RGMII.

Changes in v2:
 - Fix the wrong missed RMII phy interface mode.
 - Add Reviewed-by tag.
