This iteration addresses several issues raised by Sashiko. Some are not
addressed as they were false positives (nothing in the PHY driver ever
calls phy_runtime_get() on the parent device) or I decided they make no
sense - like the suggestion to remove the power-domain-names property
because there's only one power domain.

Add support for the firmware-managed variant of the DesignWare MAC on
the sa8255p platform. This series contains new DT bindings and driver
changes required to support the MAC in the STMMAC driver.
It also reorganizes the ethqos code quite a bit to make the introduction
of power domains into the driver a bit easier on the eye.
The DTS changes will go in separately.

Changes in v15:
- Squash patches 6 and 7 to avoid a potential hang-on-resume regression
(Sashiko)
- Fix the AUTONEG_DISABLE early return path in forced mode (Sashiko)
- Fix Kconfig dependencies on generic power domains (Sashiko)
- Set the performance level back to 0 on unbind in the PHY driver
(Sashiko)
- Use devm_pm_runtime_enable() where applicable
- Link to v14: https://patch.msgid.link/20260908-qcom-sa8255p-emac-v14-0-ec212b747a7d@oss.qualcomm.com
Changes in v14:
- let genpd's own runtime suspend/resume callbacks own the perf state entirely
by calling dev_pm_genpd_set_performance_state() in set_mode()
unconditionally in the sgmii PHY driver

setting is already synchronous
- add missing power-domains limits for ma35d1/k3-dwmac
- fix ordering of clearing the sgmii loopback
- configure the wrapper clocks synchronously in scmi setup
