net: stmmac: qcom-ethqos: use phy interface mode for inband

Browse Source 
qcom-ethqos currently forces inband to be enabled for the Cisco SGMII
speeds (1G, 100M and 10M) but not for 2500BASE-X (2.5G).

Rather than using the speed to determine the forced inband state, use
phylink's PHY interface mode which will switch between SGMII for the
10M, 100M and 1G speeds, and 2500BASE-X for 2.5G.
