No, this is board specific. It happens that our board uses the reset
value (low active), whereas all other board seem to use high active
(which is now a Kconfig option). I decided to create a config option to
set the "non-default" (reset) value, and make the reset value as new
default. I assume that the currently supported boards use high active
polarity since that was the code did before...
