[PATCH v8 1/2] Input: add ABS_SND_PROFILE

[David Heidelberg via B4 Relay <devnull+david.ixit.cz@kernel.org>]

From: Gergo Koteles <soyer@irl.hu>

ABS_SND_PROFILE used to describe the state of a multi-value sound profile
switch. This will be used for the alert-slider on OnePlus phones or other
phones.

Profile values added as SND_PROFLE_(SILENT|VIBRATE|RING) identifiers
to input-event-codes.h so they can be used from DTS.
