[PATCH] ARM: dts: vf-colibri: apply the EXT_IO pin group

From: Mehmet Fide <mehmet.fide at screeningeagle.com>

pinctrl_gpio_ext describes the three Colibri EXT_IO pins, but no node
references it, so the pin controller never applies it and the pads keep
whatever mux and bias they came up with. It is the only pin group in the
Vybrid Colibri device trees that is defined and never used.

Hog it on the pin controller, which is the usual home for pins no device
owns, so EXT_IO_0..2 are muxed as GPIO with the drive settings the group
already spells out.
