MLK-14373-4: ARM: dts: imx6ul-evk-btwifi: Fix SN8000CMK bringup error
Fix SN8000CMK bring-up error on i.MX6UL/ULL EVK’s: BT_REG_ON line pulled
low prior to SDIO initialization. This fix applies to all modules: i.e.
default operation for all modules is that both WL_REG_ON and BT_REG_ON
lines are pulled low (0V) during power-on-reset.
