Fix gcc build error while CONFIG_SND_SOC_SOF_NOCODEC=m
sound/soc/sof/core.o: In function `snd_sof_device_probe':
core.c:(.text+0x4af): undefined reference to `sof_nocodec_setup'
Change SND_SOC_SOF_NOCODEC to bool to fix this.

This change would break things severely. This won't allow to build it
as a module any longer.
A better fix would be to somehow restrict the SND_SOC_SOF_NOCODEC to
align with SND_SOC_SOF, i.e. disallow SND_SOC_SOF=y &&
SND_SOC_SOF_NOCODEC=m. Because of the complex mix of select and
depends-on in SOF, I'm afraid that it's not that trivial, though.
There might be something I overlooked, hopefully...
An easier alternative would be to replace
IS_REACHABLE(CONFIG_SND_SOC_SOF_NOCODEC). This assures the condition
at the build time, although the error at probe might be a surprising
to some users that don't know this hidden dependency.
