Subject: [PATCH 2/2] ARM: imx: mach-imx7ulp: warn when imx_soc_device_init
 fail

Follow other i.MX6/7 machince code to check return value
of imx_soc_device_init and warn when fail.

Also drop of_platform_default_populate, because
"arch_initcall_sync(of_platform_default_populate_init);" could be
used to populate the device tree.
