Fix the pinctrl and interrupt specifier for RK808 to use GPIO3_B2. On the Rockpro64 schematic [1] page 16, it shows GPIO3_B2 used for the interrupt line PMIC_INT_L from the RK808, and there's a note which translates as: "PMU termination GPIO1_C5 changed to this". Tested by setting an RTC wakealarm and checking /proc/interrupts counters. Without this patch, neither the rockchip_gpio_irq counter for the RK808, nor the RTC alarm counter increment when the alarm time is reached. With this patch, both interrupt counters increment by 1 as expected.
