dt-bindings: gpio: rockchip,gpio-bank: Add rockchip,grf property

Some Rockchip SoCs, such as the RV1106, give each GPIO bank its own
IO control (IOC) register block rather than grouping the registers of
all banks into a shared GRF region. Add an optional rockchip,grf
property to the gpio-bank binding so that each bank node can reference
the syscon for its own IOC block.
