[PATCH v1 1/3] arm64: dts: rockchip: rk3588-rock-5b-5bp-5t: Correct Type-C pin bias settings

[Anand Moon]

As pre FUSB302 datasheet interrupt line (INT_N) is an open-drain,
active-low signal. It requires a pull-up resistor to maintain a stable
high state when deasserted. Similarly, the TYPEC5V_PWREN_H enable signal
requires a pull-down resistor to ensure it defaults to a low state,
preventing unintended power delivery during the boot sequence.

Update the pinctrl entries to use pcfg_pull_up for usbc0_int and
pcfg_pull_down for vbus5v0_typec_en to align with the hardware's
electrical requirements.
