The RK3399 has a total of 9 I2C controllers. To support these, the enum in periph.h is extended and the mapping from the IRQ numbers to the peripheral-ids is extended to ensure that pinctrl requests are passed through to the function configuring the I2C pins. For I2C8, the pinctrl is implemented and tested (on a RK3399-Q7) using communication with the FAN53555 connected on I2C8.
