pinctrl: stm32: add possibility to configure pins individually

Browse source

Adds the possibility to configure a single pin through the gpiolib (i.e:
to set PULL_UP/PULL_DOWN config).
Mutex behavior is slightly changed to avoid a deadlock when pin_config_set
is called (in this case pctldev->mutex is already taken).
