TFMini on TELEM2 and MAVLINK on TELEM1 for Raspberry Pi Connection

[tahan094]

Describe the bug

First I connect TFMINI on TELEM1 and MAVLINK to TELEM2 everything is working except that the reading from the TFMini had a periodic spike. So I decided to reverse, the spikes are gone and the altitude response was very stable. But the issue is that MAVLINK is no longer working on with raspberry pi.

I just try to disable the TFMini and the connection were ok with Mavlink with Raspberry Pi through TELEM1.
I had other trial, I connected and selected the Serial4 to be used by MAVLINK and surprisingly it worked (both)
So there is in issue in TELEM1

To Reproduce

connect TFMini to TELEM2 and initiate mavlink/mavros through a companion computer to TELEM1, no connection through mavlink shall happen
