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 X-AffectedPlatforms: RK3399-Q7 Signed-off-by: Philipp Tomsich <philipp.tomsich@theobroma-systems.com> Tested-by: Jakob Unterwurzacher <jakob.unterwurzacher@theobroma-systems.com> Acked-by: Simon Glass <sjg@chromium.org>
