GNSS override is ignored for waveshare_sx1302_lorawan_gateway_hat

[errolt]

• [x] The issue is present in the latest release.
• [x] I have searched the issues of this repository and believe that this is not a duplicate.

What happened?

Setting model_flags=[ "GNSS" ] is ignored when model="waveshare_sx1302_lorawan_gateway_hat"

What did you expect?

I expected the GPS to be used. If I set model="rak_2287", with the waveshare radio still connected, then the GPS is used, even though the GPS on the module isn't UBLOX

Steps to reproduce this issue

Steps: Add GNSS for model_flags, set model to waveshare_sx1302_lorawan_gateway_hat and set log_level="DEBUG"

Could you share your log output?

With model="waveshare_sx1302_lorawan_gateway_hat"
