soc: imx8: select SOC_BUS

Compile-testing the driver can result in a link failure
when CONFIG_SOC_BUS is disabled:

x86_64-linux-ld: drivers/soc/imx/soc-imx8m.o: in function `imx8_soc_init':
soc-imx8m.c:(.init.text+0x28d): undefined reference to `soc_device_register'

Select it from Kconfig, as we do from the other SoC drivers.

          If you say yes here you get support for the NXP i.MX8M family
          support, it will provide the SoC info like SoC family,
