arm64: dts: rockchip: add pinctrl for clk-generator GPIO on rk3588-tiger

While specific driver in the Linux-Kernel handles GPIOs gracefully without
matching pinctrl entries, this might not be true for other operating
systems. So having pinctrl entries makes the hardware-description
more complete.

The somewhat similar rk3588-jaguar board has a pinctrl entry already,
so also add one for rk3588-tiger.
