ARM: dts: am437x-sk: reduce col-scan-delay-us
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. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
