MLK-11758 dts: mx6ul evk: set regulator wlreg_on always on
Murata adapter VDDIO is derived from sd slot VMMC supply, if usdhc cannot
detect sd/sdio card, VMMC is shutdown that causes VDDIO has no voltage, and
bt cannot work. So BT depends on VDDIO/VMMC.
Now the workaround is set wlreg_on alwasys on, usdhc can detect wifi card
and supply VMMC 3.3V voltage, so that Murata adapter VDDIO has power supply.
