fix: MPM module status

[raphaelcoeffic]

We should only consider whether or not the MPM has a working telemetry link.

Fixes an issue introduced in #3822

Fixes #4197, resolves #1187

This fixes the first part of the issue - TR("Disable int.", "Disable internal RF") being shown all the time on colorlcd and B&W w/ internal MPM, but now it says No telemetry as mentioned in #4197. TX16S, Zorro /w internal MPM

Ok, so it's not just the status display thingy: it actually does not have any valid telemetry status.

@pfeerick I fixed the second part (in pulses) which has also assuming that S.PORT is used, rather than checking just checking for a RX port in general.

I sneaked in an implementation for #1187 as well, as @gagarinlg was complaining 🤪

Seems to be working properly now for X9D+2019, TX16S /w MPM, Zorro /w MPM
