boards: mark gpio as supported capability where known missing

pabigot · galak · commit 2f1a0c8ae9b8 · 2019-11-13T10:43:04.000-06:00
Some board description files failed to note where gpio was supported,
causing tests to be inappropriately filtered.  Add the feature where
the gpio_basic_api test would use it.
