At Huawei Matebook D15 two different GPIOs are used to control the output:
- gpio0 controls the speaker output;
- gpio1 controls the headphone output.
Changing both at the same time cause spurious events that are mis-interpreted
as input events, causing troubles on apps. So, a delay is needed before turning
on such gpios.
With this patch, plugging a headphone causes a jack event to trigger the speaker
supply, powering down the speaker and powering up the headphone output.
Removing the headphone also triggers the power supply, powering up the speaker
and powering down the headphone.
---
v3:
- add a patch changing GPIO quirk speaker naming. Patch 2 got rebased on the top of it.

From: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com>
In preparation for the support of an additional gpio for headphone
control, rename GPIOs to make explicit references to speakers and
gpio0 or gpio1.
No functionality change.

nit-pick: these changes could be applied to the previous patch.
the rest of the code looks fine, thanks Mauro!

Based on experimental tests, Huawei Matebook D15 actually uses
both gpio0 and gpio1: the first one controls the speaker, while
the other one controls the headphone.
Add a quirk for that.
