generic: backport at803x fixes

As patches for the AR8031/AR8033 copper page selection were merged
upstream, we can backport these patches.

This also fixes a PHY capabilities detection issue on the Ubiquiti
ER-X-SFP.

-From: Roman Yeryomin <roman@advem.lv>
-Subject: kernel: add at803x fix for sgmii mode
-
-Some (possibly broken) bootloaders incorreclty initialize at8033
-phy. This patch enables sgmii autonegotiation mode.

-Add back explicit PHY feature flags for the AR8031 and
-AR8033 PHY instead of reading them from the PHY.
-
-The Botloader for Ubiquiti UniFi AC boards (and possibly more)
-leave fiber page selected, thus we will end up reading the PHY
-capabilities of the SGMII side (which does not offer 10 Mbit/s).
-
-We already have a hack in place, which switches back to the copper
-page, however this happens after capabilities are read.
-
-The original conversation about 735-net-phy-at803x-fix-at8033-sgmii-mode
-back in 2015 explicitly mention the UniFi AC Lite. The issue however is
-not missing autonegotiation on the Fiber side, but the fact the PHY
-is never switched to the copper side. So half of this patch is superfluous.
-
-A fix is currently being upstreamed. Once this is mainlined and available to us,
-these patches can be dropped:
-
-735-net-phy-at803x-fix-at8033-sgmii-mode.patch
-736-net-phy-at803x-add-at8031-features.patch
-
-This was tested on a UniFi AC Lite.
