[ Upstream commit 6c9cd59dbcb09a2122b5ce0dfc07c74e6fc00dc0 ]
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.
