Updated praline low and high band tuning (#3030)

Browse Source 
* Updated harckrf_gpio methods to more closely reflect hackrf_usb. Added some ui debug updates to RFFC5072 Status View.

* Updated tuning tables for tuning.cpp. Remnoved 15MHz lower limit in max2831.cpp since lower bandwidths don't seem to be causing lower band issues. Added more opportunities for clocks to stabalize at startup in board.cpp. Added/amended UI to help with addresssing low band tuning issues. Cleaned up stale comments in radio.cpp.

* Ran format-code.sh

* Updated to remove commented lines as part of clean up addressing review comments.
