[PATCH] ASoC: SOF: Intel: hda: enable async suspend

[Ranjani Sridharan]

The skylake driver disabled async suspend to prevent disabling
the DSP before the card was suspended during system suspend.
This code was carried over to the SOF driver. But, there is no
risk of the DSP getting disabled before the card is suspended
with the SOF driver. Therefore, it is safe to enable async suspend
and thereby optimize the system resume time.

      commit: 75c64508dfa6679f2969e68313ee4f7fbdac865b

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
