[PATCH] dt-bindings: gpio: gpio-pca9570: Add label property

[Michal Simek <michal.simek@xxxxxxx>]

Add a label property to allow a custom name to be used for identifying
a device on the board. This is useful when multiple devices are present on
the same board. Similar change was done by commit ffae65fb1ae4
("dt-bindings: spi: spi-cadence: Add label property") or by commit
a53faa6bfa3b ("dt-bindings: hwmon: ina2xx: Add label property").
