realtek: rtl9303: enable PSE on Hasivo S600WP-5GT-2SX-SE

Wire the HS104 controller (0x0d) on the PSE i2c-gpio bus and attach the
four PoE PHYs (lan1-4) via PHY_C45_PSE; lan5 is not PoE. Add the STC8 LED
MCU (0x4d) with per-port PoE LED triggers, and pull the HS104 PSE and STC8
kmods into the image.
