realtek: gs110tpp: switch to PSE driver

Browse Source 
Use the realtek-pse-mcu kernel driver instead of realtek-poe. The MCU
is a Nuvoton M05xx using the gen1 protocol over UART at 19200 baud.

realtek-poe turns off the MCU's port mapping at startup, which reversed
the PoE port numbering and the front-panel PoE LEDs. The kernel driver
leaves the mapping alone, so both now match the front panel. The MCU
keeps this state across a warm reboot, so a unit sysupgraded from a
realtek-poe image stays reversed until its first power cycle.

Tested on a GS110TPP v1: the driver probes the MCU and its BCM59121,
and a PoE device on lan1 is powered.
