    apm821xx: MBL: correct phy-mode delay settings
    
    This came up in an upstream commit: "
    b1dd9bf688b0 "net: phy: broadcom: Fix RGMII delays for BCM50160 and BCM50610M"
    
    The PHY driver entry for BCM50160 and BCM50610M calls
    bcm54xx_config_init() but does not call bcm54xx_config_clock_delay() in
    order to configuration appropriate clock delays on the PHY, fix that."
    
    So the "rgmii" phy-mode has always been wrong, but went unnoticed since
    the broadcom phy driver didn't push the delay settings to the chip.
