generic: backport at803x fixes

Browse Source 
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.

Subject: [PATCH] net: phy: at803x: select correct page on config init
The Atheros AR8031 and AR8033 expose different registers for SGMII/Fiber
as well as the copper side of the PHY depending on the BT_BX_REG_SEL bit
in the chip configure register.
The driver assumes the copper side is selected on probe, but this might
not be the case depending which page was last selected by the
bootloader. Notably, Ubiquiti UniFi bootloaders show this behavior.
Select the copper page when probing to circumvent this.

Subject: [PATCH] net: phy: at803x: fix probe error if copper page is selected
The commit c329e5afb42f ("net: phy: at803x: select correct page on
config init") selects the copper page during probe. This fails if the
copper page was already selected. In this case, the value of the copper
page (which is 1) is propagated through phy_restore_page() and is
finally returned for at803x_probe(). Fix it, by just using the
at803x_page_write() directly.
Also in case of an error, the regulator is not disabled and leads to a
WARN_ON() when the probe fails. This couldn't happen before, because
at803x_parse_dt() was the last call in at803x_probe(). It is hard to
see, that the parse_dt() actually enables the regulator. Thus move the
regulator_enable() to the probe function and undo it in case of an
error.

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:
