New versions of VA Macro has soundwire integrated, so handle the soundwire npl
clock correctly in the codec driver.

Introduce has_npl_clk and handle the sm8550 case separately because
it has soundwire integrated but doesn't have an npl clock.

Thanks!

[1/1] ASoC: codecs: va-macro: add npl clk
      commit: a6eb64e7e32c7a6a502a19c20e3f04818091c2dc

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
