Subject: [PATCH 2/2] dt-bindings: spi: spi-cadence: Add label property

Add a label property to allow a custom name to be used for identifying the
controller on a board. This is useful when there is more than one
controller present. Similar change was done by commit 412b7a521c30
("dt-bindings: eeprom: at24: Add label property for AT24").
