drivers/net/phy/m88e1512: Add downshift enable

This patch provides the functionality to enable downshift on Marvell
PHY. By setting a downshift counter, the PHY is correspondingly often
attempted to establish Gigabit link before the PHY downshifts to the
next highest speed. The range is limited to 8 trials. To activate
downshift, a software reset must follow to take effect.
