Add DMI entry for Huawei Matebook B3-420 (BDZ-WXX9) with HEADPHONE_GPIO
and HEADSET_MIC1 quirks.

Similar to Huawei Matebook D (BOD-WXX9).
On the same machine,audio routing between speakers and headphones works
correctly when running Windows with the Huawei audio driver.
However, after reinstalling Linux, both the speakers and headphones output
sound simultaneously,indicating that the amplifier enable GPIOs are not
being toggled correctly to separate the two outputs.

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
