input: snvs_pwrkey: add linux prefix for wakeup property

The wakeup capability is somehow linux specific, and all existing
bindings name the property "linux,wakeup" to reflect that, e.g.
Documentation/devicetree/bindings/input/gpio-matrix-keypad.txt.  Let's
follow the convention.

This is a fixup for Frank's patch which is queued on i.MX tree, so I
will apply it to the same branch.

I remember Dmitry Torokhov said use wakeup, instead of linux, wakeup
when I sent patch to review.

I do not believe it is Linux specific, it describes desired behavior of
hardware regardless of OS. I mean you want your device to wake up if you
press power button whether it runes Linux, Windows, FreeBSD or whatever.

I should have said to use "wakeup-source", not simply "wakeup" so that
we'd match with I2C annotation.

I think I'll go over input driver and convert them (keeping old names
for compatibility reasons).

Thanks.

Yeah, consistency is the real motivation of this patch.  I do not
like that different properties are invented for the same purpose.  As it
seems that subsystems are all moving to "wakeup-source", I would be
happy to get it consistent with that.  V2 will be coming soon.
