Since we now have proper PHY driver for the QCA807x PHY-s, lets remove
PHY handling from AR40xx.
This removes PHY driver, PHY GPIO driver and PHY init code.
AR40xx still needs to handle PSGMII calibration as that requires R/W
from the switch, so I am unable to move it into PHY driver.
This also converted the AR40xx driver to use OF_MDIO to find the MDIO
bus as it now cant be set through the PHY driver.
So lets depend on OF_MDIO in KConfig.

This adds driver for the Qualcomm QCA8072 and QCA8075 PHY-s.
They are 2 or 5 port IEEE 802.3 clause 22 compliant
10BASE-Te, 100BASE-TX and 1000BASE-T PHY-s.
They feature 2 SerDes, one for PSGMII or QSGMII connection with MAC,
while second one is SGMII for connection to MAC or fiber.
Both models have a combo port that supports 1000BASE-X and 100BASE-FX
fiber.
Each PHY inside of QCA807x series has 2 digitally controlled output only
pins that natively drive LED-s.
But some vendors used these to driver generic LED-s controlled by
user space, so lets enable registering each PHY as GPIO controller and
add driver for it.
This also adds the ability to specify DT properties so that 1000 Base-T
LED will also be lit up for 100 and 10 Base connections.
This is usually done by U-boot, but boards running mainline U-boot are
not configuring this yet.
These PHY-s are commonly used in Qualcomm IPQ40xx, IPQ60xx and IPQ807x
boards.

This reverts the usage of the S-Tag for separating LAN and WAN port on
the embedded switch. Many users complained about not being able to
manage C-Tag addition / removal on the switch as well as degraded
performance.

The target uses 5.4 as default kernel since 03/2020.
Kernel 4.19 support is not really maintained anymore, it does not
seem to be needed, and removing it will make upcoming driver
updates easier. Thus, remove it.
