ulx3s: add HDMI pins.
This commit adds the HDMI (called GDPI for licensing reasons) pins to the ULX3S platform.
The constraints were taken from https://github.com/emard/ulx3s-misc/blob/master/constraints/ulx3s_v20.lpf
The top bank of the ECP5 only support differential outputs, so make all differential pairs outputs.
