stmmac: do not call fix_mac_speed if NULL
On some platforms, fix_mac_speed is used for configuring some sysconf registers according to the working speed. This patch fixes the fix_mac_speed invocation that cannot be done if it is a NULL pointer. Signed-off-by: Giuseppe Cavallaro <peppe.cavallaro@st.com> Signed-off-by: David S.
