phy: marvell: add link partner advertised modes 



Read the standard link partner advertisment registers and store it in
phydev->lp_advertising, so ethtool can report this information to
userspace via ethtool.  Zero it as per genphy if autonegotiation is
disabled.  Tested with a Marvell 88E1512 PHY.
