pinctrl: stm32: correct management pin display of OTYPE
OTYPE can be used for output or for alternate function to select
PP = push-pull or OP = open-drain mode, according reference manual
(Table 81. Port bit configuration table).
This patch removes this indication for input pins and adds it
for AF and output pins for pinmux command output.
