setting clock rate on child clocks without a parent clock rate will
result in zero clk rate for child. This also means that when audio
is started dsp will attempt to access registers without enabling
clock resulting in board boot up.

Fix this by adding the missing parent clock rate.

Applied to

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

Thanks!

[1/1] ASoC: q6afe-clocks: Add missing parent clock rate
      commit: 7e20ae1208daaf6dad85c2dcb968fc590b6f3b99

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
