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 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.
