IMX_SCU_SOC could be enabled with COMPILE_TEST, however there is
no dummy functions when CONFIG_IMX_SCU not defined. Then there
will be build failure.
So add dummy functions to avoid build failure for COMPILE_TEST

The soc-imx8.c driver is actually for i.MX8M family, so rename it
to soc-imx8m.c.
Use CONFIG_SOC_IMX8M as build gate, not CONFIG_ARCH_MXC, to control
whether build this driver, also make it possible for compile test.
Default set it to y for ARCH_MXC && ARM64

Applied both, thanks.
