ARM: dts: imx7-colibri: add gpio-line-names
Add Colibri SODIMM numbers as GPIO line names on module level. The GPIO lines with a name are all available on the SODIMM edge connector of the Colibri iMX7 module and therefore a customer might use it as a GPIO. The Toradex Evaluation Board has the SODIMM numbers printed on the silk- screen. This allows a customer to quickly control a GPIO on a pin-header by using the name printed next to it. Putting the GPIO line name on module level makes sure that a customer gets a reasonable default. If more meaningful names are available on a custom carrier board, the user can overwrite the line names in a carrier board level device tree. The eMMC based modules share all GPIO names except two GPIOs on bank 6 which are not available on the raw NAND devices. Hence overwrite GPIO line names of bank 6 in the eMMC specific device tree file.
