This looks upside down. You should select SOF_DT first then include the
NXP stuff.

One more thing: So this should be 'depends on SND_SOC_SOF_DT' right?

I would do this:

config SND_SOC_SOF_DT
tristate "SOF DT enumeration support"
depends on OF # or whatever the top-level DT dependency is
select SND_SOC_SOF
select SND_SOC_SOF_OPTIONS


config SND_SOC_SOF_IMX_TOPLEVEL
bool "SOF support for NXP i.MX audio DSPs"
depends on ARM64 && SND_SOC_SOF_DT || COMPILE_TEST

if SND_SOC_SOF_IMX_TOPLEVEL

config SND_SOC_SOF_IMX8
tristate "SOF support for i.MX8"

In other words push the dependencies at a higher level.
