[PATCH 6/7] ARM: dts: add gpio-ranges property to iMX6UL GPIO controllers

To establish a connection between GPIO controllers and pin multiplexor
controller add gpio-ranges properties to all GPIO controllers found
on iMX50 SoC. The change was done after human parsing of output from

% gawk -n '{ sub(/.*__/, ""); if ($1 ~ "^GPIO") print $1, $2/4}' imx6ul-pinfunc.h | sort -n
