e9431a8335 ipq40xx: fix ar40xx driver
This commit is completely based on the work of adron-s:
https://github.com/openwrt/openwrt/pull/4721#issuecomment-1101108651

The commit fixes the data corruption on TX packets. Packets are
transmitted, but their contents are replaced with zeros. This error is
caused by the lack of guard (50 ms) intervals between calibration phases.
This error is treated by adding mdelay(50) to the calibration function
code. In the original qca-ssda code [0], these mdelays were existing, but
in the ar41xx.c they are gone.

Tested on:
- Fritz!Box 4040
- Fritz!Box 7530
- Mikrotik SXTsq 5AC
- ZyXEL NBG6617

da7ef7f414 ipq40xx: net: phy: qca807x: fix GPIO driver
While rebasing into setting bits instead of magic values,
I accidentally forgot to actually set the force bit.

Without it using the pins as GPIO-s did not actually work.

fd033364f6 ipq40xx: net: ethernet: edma: use generic PHY print
Lets use the generic upstream phy_print_status() instead of doing 
something similar by hand.

Before:
ess_edma c080000.edma: eth1: GMAC Link is up with phy_speed=1000

After:
ess_edma c080000.edma eth1: Link is Up - 1Gbps/Full - flow control rx/tx

9d69505194 ipq40xx: net: ethernet: edma: use generic ksettings functions
Since we now have a proper PHY driver for QCA807x and AR803x has already
been supported properly there is no need for the driver to be poking
on PHY registers for ethtool ops.

So, lets simply use the generic
phy_ethtool_ksettings_get/phy_ethtool_ksettings_set functions.

This also has the advantage of properly populating stuff other than
speeds like, transceiver type, MDI-X etc.

PHY needs to be soft reset before starting it from ethernet driver as
AR40xx calibration will leave it in unwanted state.

26b1f72381 ipq40xx: net: phy: ar40xx: remove PHY handling
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.

b5c93edd74 ipq40xx: add Qualcomm QCA807x driver
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.

03bae3cafd ipq40xx: edma: convert to of_mdio_find_bus()
With the reworked MDIO driver, EDMA will fail to get the MII BUS as it
used the MII BUS stored inside the MDIO structure private data.

This obviously does not work with the modernized driver, so lets switch
to using a purpose build of_mdio_find_bus() which will return the MII
BUS and only requires the MDIO node to be passed.
This is easy as we already have the node parsed.

Also, since we now require OF_MDIO add that as dependency.

cdc8d4b46f ipq40xx: revert usage of VLAN S-TAG
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.

e73d866c6f ipq40xx: enable RX hash / CTAG TX offloading for single-phy
This re-enables offloading features disabled by
commit 9da2b56760 ("ipq40xx: fix ethernet vlan double tagging").

Single-PHY devices use port-based VLANs on the switch, therefore no
S-TAG magic is involved here. Re-enabling these features restores
throughput back to 950 Mbit/s.

a7afeb3142 ipq40xx: remove support for kernel 4.19
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.
