[PATCH] dt-bindings: mtd: ti,gpmc-nand: Add missing 'rb-gpios'

[Rob Herring]

With 'unevaluatedProperties' support implemented, the TI GPMC example
has a warning:

Documentation/devicetree/bindings/memory-controllers/ti,gpmc.example.dt.yaml: nand at 0,0: Unevaluated properties are not allowed ('rb-gpios' was unexpected)

Add the missing definition for 'rb-gpios'.
