[PATCH 2/2] soc: imx: soc-imx8: Correct return value of error handle

[Anson Huang <anson.huang@nxp.com>]

Current implementation of i.MX8 SoC driver returns -ENODEV
for all cases of error during initialization, this is incorrect.
This patch fixes them using correct return value according
to different errors.
