platforms: fix Colorlight i9+ DIMM pinout

Correct the DIMM connector against the published Colorlight i9+ v6.1 pinout. This fixes the ETH1_2N separator and marks the documented NC/GND positions accordingly.

Source: Colorlight i9+ v6.1 pinout (https://github.com/wuxx/Colorlight-FPGA-Projects/blob/master/colorlight_i9plus_v6.1.md).
