Subject: [PATCH RFC 2/2] ASoC: Intel: sof_es8336: Huawei Matebook D15 uses a headphone gpio

From: Mauro Carvalho Chehab <mchehab+huawei@...nel.org>

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.
