…S8830 retimers On the Purwa IoT EVK, each PS8830 retimer has its own 25 MHz crystal wired to the retimer's XI/XO pins. The reference clock does not come from the PMIC, so the RPMH_RF_CLK4/5 references in the retimer nodes are wrong: they keep those RF clocks enabled for nothing and describe a connection that does not exist on the board. Remove the stale "Left unused" annotation from the vreg_rtmr0 regulators as the retimer is actively used.

…timer 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.
