Bartosz Golaszewski a9aaf1ff88 power: sequencing: request the WLAN enable GPIO as-is 
If the WCN module is powered up before linux boots and the ath11k driver
probes at the same time as the power sequencing driver, we may end up
driving the wlan-enable GPIO low in the latter, breaking the start-up of
the WLAN module. Request the wlan-enable GPIO as-is so that if the WLAN
module is already starting/started, we leave it alone.
