Update all the code that use soc_device_match because add support for
soc_device_match returning -EPROBE_DEFER.

When imx8_soc_info_driver uses module_platform_driver() to regitser
itself, the caam driver cannot identify the SoC in the machine because
the SoC driver is probed later, so that add return -EPROBE_DEFER.

In i.MX8M boards, the registration of SoC device is later than caam
driver which needs it. Caam driver needs soc_device_match to provide
-EPROBE_DEFER when no SoC device is registered and no
early_soc_dev_attr.

In patch "soc: imx8m: change to use platform driver", change soc-imx8m.c to use
module platform driver and use NVMEM APIs to ocotp register, the reason is that
directly reading ocotp egister causes kexec kernel hang because kernel will
disable unused clks after kerne
Hi,
Thanks for reporting this issue, I'll check and add a fix to handle defer probe.
Best regards,
