power: sequencing: request the WLAN enable GPIO as-is

Browse Source 
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.
