debug: revert forced gpio lock

ref. 8ceeebdb24
does not really do much, just causes yet another 'why does this driver
ignores pin 1 or 3' question by anyone trying to use buttons or relays

since we configure pins on per-driver basis and dont have global
'roles' assigned to each pin, it is pretty tricky to understand every
other dependency coming in at setup() time. right now, first one wins.

a bit more complex pre-setup() dependency resolution could also work,
and some concept that we depend on uart as peripheral and not just some pins
