Revert "net: ethernet: qualcomm: Remove QDF24xx support"

This reverts commit a2a7f98aeeec48118fac73c22bd54f8889815e16.

Konrad mentioned that Qualcomm appears to use these devices, still,
internally, even tho they never made it to the broader market.

net: ethernet: qualcomm: Remove QDF24xx support

This SoC family was destined for server use, featuring Qualcomm's very
interesting Kryo cores (before "Kryo" became a marketing term for Arm
cores with small modifications). It did however not leave the labs of
Qualcomm and presumably some partners, nor was it ever productized.

Remove the related drivers, as they seem to be long obsolete.

net: qcom/emac: rename emac_phy to emac_sgmii and move it

The EMAC has an internal PHY that is often called the "SGMII". This
SGMII is also connected to an external PHY, which is managed by phylib.
These dual PHYs often cause confusion. In this case, the data structure
for managing the SGMII was mis-named and located in the wrong header file.

Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies
to the internal PHY only. It also also moved from emac_phy.h (which
supports the external PHY) to emac_sgmii.h (where it belongs).

To keep the changes minimal, only the structure name is changed, not
the names of any variables of that type.

net: qcom/emac: move phy init code to separate files

The internal PHY of the EMAC differs on each SOC, and the list will
only continue to grow. By separating the code into individual files,
we can add support for more SOCs more cleanly.

Note: The internal PHY is also sometimes called the SGMII device.

We also stop referring to the various PHY variations by version number,
so no more "v2", "v3", etc. Instead, the devices are named after the
SOC they are, which is in sync with the device tree property names.

Future patches will probably rearrange more code among the files.
