net: stmmac: qcom-ethqos: remove phy_set_mode_ext() after phy_power_on()

The call to phy_set_mode_ext() after phy_power_on() was a work-around
for the qcom-sgmii-eth SerDes driver that only re-enabled its clocks on
phy_power_on() but did not configure the PHY. Now that the SerDes driver
fully configures the SerDes at phy_power_on(), there is no need to call
phy_set_mode_ext() immediately afterwards.

This also means we no longer need to record the previous operating mode
of the driver - this is up to the SerDes driver. In any case, the only
thing that we care about is the SerDes provides the necessary clocks to
the stmmac core to allow it to reset at this point. The actual mode is
irrelevant at this point as the correct mode will be configured in
ethqos_mac_finish_serdes() just before the network device is brought
online.
