Fix logger uart conflict check (#858)

Browse source 
* Fix logger uart conflict check

* Fix class for check func

* Fix syntax

Hope lint is OK with moving the end of the conditional outside the #IFDEF

* Move end of conditional inside ifdef and remove extra whitespace

* Simplify

clang-format did not like the ifdefs and was reformatting in a way that killed clang-tidy.

Simple solution is to use logger's hw_serial as source of truth

Also simplifies the code - uart doesn't need to know what the logger uart settings mean
