Subject: [PATCH] MLK-25678 arm64: dts: imx8ulp-evk: change ONOFF key to gpio
key
Since ONOFF key release status can't be detect on i.mx8ulp which means
long press can't be detect in Android, use another gpio key PTF31(SW4)
to sense ONOFF key. Besides, Vol+/- keys change to rpmsg key SW7/SW8 to
meet the requirement of Android changing volume during low power audio
playback while kernel maybe in suspend, and only PTF7(SW2) in APD side
could wake up from DSM. So move Vol+/- to RTD domain.
