[PATCH 6/6] arm64: dts: rockchip: add pinctrl for clk-generator gpio on rk3588-tiger

[Heiko Stuebner]

Having pinctrl entries defined for used gpios is helpful as it makes
sure the pin isn't used anywhere else.

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