regulator: giving regulator controlling gpios a non-empty label when used through the devicetree.
When the label is empty, it causes missing information and limits diagnostics for instances such as 'cat /sys/kernel/debug/gpio' Setting the label to the regulator supply_name will point to the device using the gpio(s).
