mt76: mt7603: add upper limit for dynamic sensitivity minimum receive power
If the minimum power is raised too much, it can make it impossible for weaker
clients to connect, and there are some scenarios where the false detects will
not go down no matter how much the sensitivity is adjusted.
Fixes connectivity issues in some rare cases
