platform/x86: asus-wmi: Disable OOBE state after resume from hibernation

[ Upstream commit 77bdac73754e4c0c564c1ca80fe3d9c93b0e715a ]

ASUS firmware resets OOBE state during S4 suspend, so the keyboard
blinks during resume from hibernation. This patch disables OOBE state
after resume from hibernation.
