realtek: XikeStor SKS8300-12E2T2X: fix GPIO assignments

Browse Source 
The initial bringup missed two GPIO-related settings:
  - TX Disable GPIO for the SFP modules
  - LED Sync GPIO selection for the port LEDs

This adds the missing TX Disable GPIOs and muxes GPIO18 to LED sync
(there are HC595 shift registers on the board that require the sync).
