arm64: dts: qcom: ipq5018: Add GE PHY to internal mdio bus

Browse source

The IPQ5018 SoC contains an internal GE PHY, always at phy address 7.
As such, let's add the GE PHY node to the SoC dtsi.

The LDO controller found in the SoC must be enabled to provide constant
low voltages to the PHY. The mdio-ipq4019 driver already has support
for this, so adding the appropriate TCSR register offset.

In addition, the GE PHY outputs both the RX and TX clocks to the GCC
which gate controls them and routes them back to the PHY itself.
So let's create two DT fixed clocks and register them in the GCC node.
