net: phy: avoid setting unsupported EEE advertisments
We currently allow userspace to set any EEE advertisments it desires,
whether or not the PHY supports them. For example:
# ethtool --set-eee eth1 advertise 0xffffffff
# ethtool --show-eee eth1
EEE Settings for eth1:
EEE status: disabled
Tx LPI: disabled
Supported EEE link modes: 100baseT/Full
1000baseT/Full
10000baseT/Full
Advertised EEE link modes: 100baseT/Full
1000baseT/Full
1000baseKX/Full
10000baseT/Full
10000baseKX4/Full
10000baseKR/Full
Clearly, this is not sane, we should only allow link modes that are
supported to be advertised (as we do elsewhere.) Ensure that we mask
the MDIO_AN_EEE_ADV value with the capabilities retrieved from the
MDIO_PCS_EEE_ABLE register.
