arm: boot: dts: am437x-sk: fix for new newhaven display module revision

AM437x Starter Kit uses a NewHaven Display module with a 4.3" display and EDT FT5306 touchscreen

On that module's new revision, NewHave decided to change the pinout on the 6 pin flat-pcb touchscreen connector so that instead of having WAKE pin, we now have RESETn.

The new display module is available on AM437x SK Beta and all new revisions while the older revision is only available on AM437x SK Alpha which, unfortunately, can't be supported anymore in mainline without a revert of this patch.

The new AM437x SK Beta boards have removed the large capacitors on the gpio-matrix column lines which means we can reduce col-scan-delay-us to 5us without loosing functionality.
