net: phy: fix marvell phy status reading
commit 898805e0cdf7fd860ec21bf661d3a0285a3defbd upstream.
The Marvell driver incorrectly provides phydev->lp_advertising as the
logical and of the link partner's advert and our advert. This is
incorrect - this field is supposed to store the link parter's unmodified
advertisment.
This allows ethtool to report the correct link partner auto-negotiation
status.
