ipq40xx: 6.1: use latest DSA and ethernet patches 
This pulls-in the latest version of qca8k based IPQ4019 driver as well as
the latest version of IPQESS that was sent upstream.

Both qca8k and IPQESS have been improved and cleaned up compared to current
version of patches.

PSGMII PHY mode and missing reset have been upstreamed and will be in
the kernel 6.6.

Subject: [PATCH] net: dsa: qca8k: add IPQ4019 built-in switch support
Qualcomm IPQ40xx SoC-s have a variant of QCA8337N switch built-in.
It shares most of the stuff with its external counterpart, however it is
modified for the SoC.
Namely, it doesn't have second CPU port (Port 6), so it has 6 ports
instead of 7.
It also has no built-in PHY-s but rather requires external PSGMII based
companion PHY-s (QCA8072 and QCA8075) for which it first needs to carry
out calibration before using them.
PSGMII has a SoC built-in PHY that is used to connect to the PHY-s which
unfortunately requires some magic values as the datasheet doesnt document
the bits that are being set or the register at all.
Since its built-in it is MMIO like other peripherals and doesn't have its
own MDIO bus but depends on the SoC provided one.
CPU connection is at Port 0 and it uses some kind of a internal connection
and no traditional RGMII/SGMII.
It also doesn't use in-band tagging like other qca8k switches so a out of
band based tagger is used.
