stmmac_mdio_reset() has been updated to use msleep rather udelay (as some PHY requires a one second delay there). It called from stmmac_resume() within the spin_lock_irqsave block atomic context triggering 'scheduling while atomic'. The stmmac_priv lock usage is not fully documented, but it seems to protect the access to the MAC registers / DMA structures rather than the MDIO bus or the PHY (which have separate locking), so we can push the spin_lock after the stmmac_mdio_reset call.
