[PATCH] ARM: DTS: da850: fixed missing #gpio-cells in gpio node

[Petr Kulhavy]

The gpio node was missing the mandatory property #gpio-cells, which was
causing runtime errors when using GPIOs e.g. with gpio-leds or gpio-keys:

"could not get #gpio-cells for /soc/gpio@1e26000"

This fixes the problem and adds the missing parameter.
The value is 2 according to the gpio-davinci.txt binding.

Thanks for the patch. Queuing this for v4.7 since it has been this way
since beginning and there seem to be no in-kernel device-tree files with
a gpio consumerm, so no one seems to be immediately affected.

Thanks,
Sekhar
