This adds device tree bindings for the Hycon HY46XX touchscreen series.

Signed-off-by: Giulio Benetti <giulio.benetti@benettiengineering.com>
---
V1->V2:
As suggested by Rob Herring:
* fixed $id: address
* added "hycon," in front of every custom property
* changed all possible property to boolean type
* removed proximity-sensor-switch property since it's not handled in driver
V2->V3:
As suggested by Jonathan Neuschäfer:
* fixed some typo
* fixed description indentation
* improved boolean properties descriptions
* improved hycon,report-speed description
V3->V4:
* fixed binding compatible string in example as suggested by Jonathan Neuschäfer
V4->V5:
As suggested by Rob Herring:
* drop hycon- prefix from compatible
* use Hertz unit suffix for hycon,report-speed instead of u32
* set hycon,report-speed minimum to 1Hz, 0Hz make controller to do nothing
* change hycon,power-noise-enable property name to hycon,noise-filter-enable
* improve hycon,filter-data property description
* use generic touchscreen node name in example
V5->V6:
* changed report-speed property name into report-speed-hz according to
Rob Herring's suggestion

I've sent v7[1] before receiving your Reviewed-by.
Do I have to re-submit it once and if I receive a Reviewed-by from you 
as a v8 with all your Reviewed-by's?

Sorry for the noise.

I gave it on v7 too, so only if there are other changes on any of the
patches. The tools will generally pick up any tags on the version
applied. You just can't expect maintainers to go rummage thru old
versions to find any tags.

Ah ok, thank you.

Sure not, this is the reason why I’ve asked, I’ve forgotten to add some tag to my commits that I usually do, that’s why I’ve messed things up.

Thank you again for reviewing and explaining me.
