Shiji Yang c60dd7bef9 ath79: rename and sort patches by OpenWrt naming rules
The patches in the ath79 target have not been sorted for a long time
and they are very chaotic now. This patch sorts them again according
to the OpenWrt naming rules[1], so that we can better manage them.

Subject: [PATCH] ath79: force SGMII SerDes mode to MAC operation
The mode on the SGMII SerDes on the QCA9563 is 1000 Base-X by default.
This only allows for 1000 Mbit/s links, however when used with an SGMII
PHY in 100 Mbit/s link mode, the link remains dead.
This strictly has nothing to do with the SerDes calibration, however it
is done at the same point in the QCA reference U-Boot which is the
blueprint for everything happening here. As the current state is more or
less a hack, this should be fine.
This fixes the issues outlined above on a TP-Link EAP-225 Outdoor.
