Subject: [PATCH net-next 5/8] net: dsa: b53: Configure RGMII for 531x5 and MII for 5325

Call b53_adjust_531x5_rgmii() and b53_adjust_5325_mii() from
b53_phylink_mac_config() when we have a fixed PHY in preparation for removing
b53_adjust_link(). Also move b53_adjust_63xx_rgmii() to
b53_phylink_mac_config() where it logically belongs.
