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

  This reverts commit 014fdeb0d747304111cfecf93df4407c1a0c80db.

Commit 014fdeb0d747 ("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().

Not sure what the proper arrangement would be, but this gets my builds
going again.

Oh, I have re-done the compile test and that does not detect this (I
don't have ARM device to runtime test it), but looks valid.
I wonder if we should do this similarly to acpi machine select via ops
to cut the circular dependency?
That can be done in a followup patch.

Please include human readable descriptions of things like commits and
issues being discussed in e-mail in your mails, this makes them much
easier for humans to read especially when they have no internet access.
I do frequently catch up on my mail on flights or while otherwise
travelling so this is even more pressing for me than just being about
making things a bit easier to read.

Applied to

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git for-next

Thanks!

[1/1] ASoC: SOF: Move sof_of_machine_select() to core.c from sof-of-dev.c
      commit: d0ae9dc48e24f5f704abcbb2dca3e4651bf0ff59

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

This doesn't apply against current code, please check and resend.
