arm64: dts: rockchip: rk3588s-tablet: add fusb302 interrupt gpio configuration for uboot

Browse Source 
The uboot Type-C PD driver needs to poll the interrupt gpio level,
but the uboot code does not have a suitable interface to convert the
attributes of "interrupt-parent" and "interrupts" to standard gpio,
so add int-n-gpios configure for uboot to analyze and use.
