arm64: dts: qcom: hamoa-iot-evk: switch typec0 to PS8830 retimer
The Hamoa IoT EVK hardware design uses a Parade PS8830 retimer on
I2C3 for USB Type-C port 0. Describe the retimer and route typec0
through it to enable USB 3.0 SuperSpeed and DisplayPort Alt Mode.
Supply the PS8830 from the existing vreg_rtmr0_* rails and remove
their stale "Left unused" annotation.
The FSUSB42 SBU mux chip is present on the PCB but with all signal
lines unconnected (NC), so remove the fsusb42 node and its pinctrl
group. The chip is retained as a hardware fallback: should the PS8830's
SBU path encounter issues, the FSUSB42 can be activated with a simple
rework, avoiding a full board respin.
