[PATCH net-next v2 7/9] net: stmmac: qcom-ethqos: set initial RGMII link clock to lowest speed

[Mohd Ayaan Anwar]

On probe the RGMII link clock is initialised at SPEED_1000, which
translates to a 250 MHz source clock even when no PHY link is present,
drawing unnecessary power.

Initialise at SPEED_10 instead; fix_mac_speed updates the rate once
a link is established.
