After reset, the debug GPIO pins (PA13, PA14, PA15, PB3, PB4) are in AF0 mode. This commit fixes the `gpio` code to reflect this.

After reset, the debug GPIO pins (PA13, PA14, PA15, PB3, PB4) are in AF0
mode. This PR fixes the
gpiocode to reflect this.I've checked all the relevant RMs to verify this. It's easiest to just look at the reset values of the
GPIOx_MODERregister. Also all the RMs say "The debug pins are in AF pull-up/pull-down after reset".
