net: phy: dp83869: Fix MII mode failure
The DP83869 driver sets the MII bit (needed for PHY to work in MII mode) only if the op-mode is either DP83869_100M_MEDIA_CONVERT or DP83869_RGMII_100_BASE. Some drivers i.e. ICSSG support MII mode with op-mode as DP83869_RGMII_COPPER_ETHERNET for which the MII bit is not set in dp83869 driver. As a result MII mode on ICSSG doesn't work and below log is seen. TI DP83869 300b2400.mdio:0f: selected op-mode is not valid with MII mode icssg-prueth icssg1-eth: couldn't connect to phy ethernet-phy@0 icssg-prueth icssg1-eth: can't phy connect port MII0 Fix this by setting MII bit for DP83869_RGMII_COPPER_ETHERNET op-mode as well.
