ARM: imx: use device_initcall for imx_soc_device_init
This is preparation to move imx_soc_device_init to drivers/soc/imx/ There is no reason to must put dt devices under /sys/devices/soc0, they could also be under /sys/devices/platform, so we could pass NULL as parent when calling of_platform_default_populate. Following soc-imx8.c soc-imx-scu.c using device_initcall, need to change return type to int type for imx_soc_device_init.
