The change corrects an example in device tree documentation section,
because button/key device nodes don't contain reg property there is
no need to declare unit-address, and address and size cell properties
are also redundant.
At the moment a compilation of the hypothetical original example
should produce W=1 level warnings, and it is better to stop spreading
misusage of the polled gpio keys device tree binding through this
example.

Pull DeviceTree updates from Rob Herring:
"A fairly large (by DT standards) pull request this time with the
majority being some overdue moving DT binding docs around to
consolidate similar bindings.
- DT binding doc consolidation moving similar bindings to common
locations. The majority of these are display related which were
scattered in video/, fb/, drm/, gpu/, and panel/ directories.
- Add new config option, CONFIG_OF_ALL_DTBS, to enable building all
dtbs in the tree for most arches with dts files (except powerpc for
now).
- OF_IRQ=n fixes for user enabled CONFIG_OF.
- of_node_put ref counting fixes from Julia Lawall.
- Common DT binding for wakeup-source and deprecation of all similar
bindings.
- DT binding for PXA LCD controller.
- Allow ignoring failed PCI resource translations in order to ignore
64-bit addresses on non-LPAE 32-bit kernels.
- Support setting the NUMA node from DT instead of only from parent
device.
- Couple of earlycon DT parsing fixes for address and options"

This patch marks all the reference to the legacy wakeup bindings
and replaces them with the standard "wakeup-source" property.
All these legacy property are also listed under a separate section in
the generic wakeup-source binding document.

This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver.
The driver already allows specifying what type of events (key / rel / abs)
a button generates when pressed, but for rel / abs axis we also need to
specify which value this specific gpio represents.
One use case is digital joysticks / direction-pads which are hooked up to
gpio, in this case we've left and right buttons which we want to map to
EV_ABS, ABS_X and we want generate events for left with a value of -1 and
for right with a value of +1 (and similar for up / down and ABS_Y).

Wakeup property of device is not Linux-specific, it describes intended
system behavior regardless of the OS being used. Therefore let's drop
"linux," prefix, and, while at it, use the same name as I2C bus does:
"wakeup-source".
We keep parsing old name to keep compatibility with old DTSes.
