Pull power sequencing fix from Bartosz Golaszewski:
"A follow-up fix for the power sequencing subsystem. It turned out the
previous fix for this driver was incomplete and broke the WLAN support
on some platforms. This addresses the issue.
- set the direction of the wlan-enable GPIO to output after
requesting it as-is"
