[PATCH v2 RESEND 0/2] Make headphone work on Huawei Matebook D15

[Mauro Carvalho Chehab]

(resent, as the From/SoB at the patches were using my past e-mail. No changes here,
except by having Hans ack and have the From/SoB fixed)

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.
