ASoC: SOF: Move sof_of_machine_select() to core.c from sof-of-dev.c

Commit 014fdeb ("ASoC: SOF: Move sof_of_machine_select() to
sof-of-dev.c from sof-audio.c") caused a circular dependency between
the snd_sof and snd_sof_of modules:

	depmod: ERROR: Cycle detected: snd_sof -> snd_sof_of -> snd_sof
	depmod: ERROR: Found 2 modules in dependency cycles!

Move the function back with sof_machine_select().

Fixes: 014fdeb ("ASoC: SOF: Move sof_of_machine_select() to sof-of-dev.c from sof-audio.c")
