This is v2 of the series enabling the two MDIO buses on the IPQ5018
platform. v1 (this series' patch 1) added TLMM pinctrl for the
external MDIO bus (mdio1) and is still under review upstream; it is
carried into this v2 with a clarified commit message noting that the
MDIO pin configuration is identical across all IPQ5018 RDP boards.
v2 adds a second patch that actually makes use of the MDIO buses on
the RDP432-c2 board: it enables mdio0, used by the SoC-integrated
EPHY, and mdio1, used by an external QCA8081 PHY, and describes the
QCA8081 PHY node on mdio1.

Changes in v3:
- Enable the SoC-integrated EPHY MDIO bus by default in the SoC-level
DTSI, and move this change into a separate patch.
- Add a blank line before the `status` property for improved formatting.

Changes in v2:
- Patch 1 (pinctrl for MDIO bus): no functional change; commit message
clarified to note the MDIO pin configuration is identical across all
IPQ5018 RDP boards.
- Patch 2 (enable MDIO buses and add ethernet PHY) is new in v2.
