arm64: dts: apalis-imx8: keep pad-wakeup instead of gpio-keys

Resume from freeze state generated non-assigned gpio interrupt
from the port in S0/S3 mode. Wakeup-source in gpio-keys
doesn’t really work for Apalis imx8qxp and Apalis imx8qm.

These targets should perform wakeup by the means of pad-wakeup
(see CONFIG_GPIO_MXC_PAD_WAKEUP implemented in gpio-mxc driver).

Kernel trace can be easily reproduced with the following scenario:
- echo freeze > /sys/power/state
- Wake the system up connecting MXM3_37 to GND.

Drop gpio-keys support for these targets and keep only pad-wakeup configured
for resume operations. More information can be found  on NXP community link
