[PATCH v3] drivers: gpio: put virtual gpio device into their own submenu

["Enrico Weigelt, metux IT consult" <info@xxxxxxxxx>]

Since we already have a few virtual GPIO drivers, and more to come,
this category deserves its own submenu.

changes v2: fixed menu title (replaced "devices" by "drivers")
changes v3: added patch changelog
