Add GPIO-controlled fixed regulators providing WLAN 3.3V and 1.8V
power rails for the Arduino VENTUNO Q board. The regulators are
enabled at boot to support WLAN initialization.

Tell us something, how is the WiFi wired and powered up? Is there a
correspoding BT, which isn't mentioned here?

GPIO56 is used for wlan_en, and GPIO54 is used for wlan_rf_kill.
BT-related GPIO configurations will be submitted in a separate patch.
