rockchip: pinctrl: rk3399: add support for the SPI5 controller
This commit adds support for the pin-configuration of the SPI5
controller of the RK3399 through the following changes:
* grf_rk3399.h: adds definition for configuring the SPI5 pins
in the GPIO2C group
* periph.h: defines PERIPH_ID_SPI3 through PERIPH_ID_SPI5
* pinctrl_rk3399.c: adds the reverse-mapping from the IRQ# to
PERIPH_ID_SPI5; dispatches PERIPH_ID_SPI3
through SPI5 to the appropriate pin-config
function; implements the pin-configuration
for PERIPH_ID_SPI5 using the GPIO2C group
