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.

Hi,
was there not an issue on some of the older ralink silicon versions that
made irq unreliable, which is why we never changed this ?
John
this only touches the mtk silicon ...
I obviously cannot prove that this will work on all devices, but I have seen
several device support PRs for mt7620/mt7621/mt7628 with gpio-keys working
(=tested) over the last half year.
I intentionally only included mt76xx here, as I have no idea whether this will
work on rtxxxx, and if I remember correctly 100 % of them still have
gpio-keys-polled set.
Best
Adrian
the code works reliably on mt76xx silicon, some of the older silicon did
not have functional irq on all pins
