net: stmmac: Power up SERDES after the PHY link
[ Upstream commit a46e9010124256f5bf5fc2c241a45cf1944b768e ]
The Tegra MGBE ethernet controller requires that the SERDES link is
powered-up after the PHY link is up, otherwise the link fails to
become ready following a resume from suspend. Add a variable to indicate
that the SERDES link must be powered-up after the PHY link.
