[PATCH V2] input: da9063: report KEY_POWER instead of KEY_SLEEP during power key-press

[Steve Twiss <stwiss.opensource@diasemi.com>]

From: Steve Twiss <stwiss.opensource@diasemi.com>

Stop reporting KEY_SLEEP for a short key-press and report KEY_POWER instead
This change applies to both DA9063 and DA9062 ONKEY drivers.

A previous application used for testing by the developer required a KEY_SLEEP
and KEY_POWER input_report_key event to distinguish between a short and
long key-press of the power key.
This is not the general convention and the typical solution is for KEY_POWER
to be used in both cases: suspend and S/W power off.

This patch applies against linux-next and v4.4-rc4

Dmitry,

Now I realise what you meant in a previous review of this driver.

- https://lkml.org/lkml/2015/4/17/618
> Why do we handle KEY_POWER and KEY_SLEEP completely differently?

Because my testing assumed KEY_SLEEP was linked to suspend and KEY_POWER was
linked to S/W power off

- https://lkml.org/lkml/2015/4/29/406
> (1) short press & release -- SLEEP
> (2) long press & release -- POWER

This change removes the reporting of KEY_SLEEP that was specific to my test
framework and replaces it with the intended KEY_POWER.
