[PATCH v2 4/4] arm64: dts: rockchip: Make Jaguar PCIe-refclk pin use pull-up config

[Heiko Stuebner <heiko@sntech.de>]

From: Heiko Stuebner <heiko.stuebner@cherry.de>

Different to RK3588-Tiger, on RK3588-Jaguar the signal enabling the
PCIe-refclk generator controls a transistor which in turn controls the
output-enable input of the PI6C557 and there's no external Pull-Up or
Pull-Down between the SoC and the transistor gate.

On Tiger the pin is directly connected to the PDn input which has an
internal pull up.

So match that behaviour on Jaguar by changing the pin config to enable
the SoC's pull-up config.
