Backport realtek phy driver changes for RTL8125D (#4014)

Browse Source 
As pointed out in [1] by @cdce8p, the RTL8125D has an internal PHY that also
needs some changes to be backported.

Also, move the patches to more targeted directories is it would be otherwise
applied to RPi 6.6 kernel with failures. We can move it back to the top-level
patches directory once RPi moves to kernel 6.12.

Subject: [PATCH] net: phy: realtek: merge the drivers for internal NBase-T
PHY's
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Realtek RTL8125/RTL8126 NBase-T MAC/PHY chips have internal PHY's
which are register-compatible, at least for the registers we use here.
So let's use just one PHY driver to support all of them.
These internal PHY's exist also as external C45 PHY's, but on the
internal PHY's no access to MMD registers is possible. This can be
used to differentiate between the internal and external version.
As a side effect the drivers for two now external-only drivers don't
require read_mmd/write_mmd hooks any longer.

Subject: [PATCH] net: phy: realtek: add RTL8125D-internal PHY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The first boards show up with Realtek's RTL8125D. This MAC/PHY chip
comes with an integrated 2.5Gbps PHY with ID 0x001cc841. It's not
clear yet whether there's an external version of this PHY and how
Realtek calls it, therefore use the numeric id for now.

This adds support for new chip version RTL8125D, which can be found on
boards like Gigabyte X870E AORUS ELITE WIFI7. Firmware rtl8125d-1.fw
for this chip version is available in linux-firmware already.

From 7ab842c714924784cae4b6ab229997905b096b4f Mon Sep 17 00:00:00 2001

Subject: [PATCH] net: phy: realtek: add RTL8125D-internal PHY
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The first boards show up with Realtek's RTL8125D. This MAC/PHY chip
comes with an integrated 2.5Gbps PHY with ID 0x001cc841. It's not
clear yet whether there's an external version of this PHY and how
Realtek calls it, therefore use the numeric id for now.
