This converts all remaining devices to use interrupt-driven
gpio-keys compatible instead of gpio-keys-polled.
The poll-interval is removed.

While at it, add/remove newlines in keys and leds node where
necessary.

I'm just wondering what makes you so confident, that this changes wont break
any of the affected devices. On which devices this has been tested? Some
Tested-by: would help to get this merged, thanks.

Well, for quite some time already every device added to ath79 and ramips has been advised to use gpio-keys, and I personally do not remember a single case where issues with that have been reported (that were not also present with polled keys).

Also note that I only address mt762x devices here, and do not touch the rtxxxx subtargets.

But I would obviously also be happy about some Tested-by from the list (as with ath79, where I received those).

Best

Adrian
