Add pins, groups, and functions for the Quad SPI Controllers on the Renesas R-Car S4-8 (R8A779F0) SoC. Based on a larger patch in the BSP by LUU HOAI. Signed-off-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx> --- v2: - No changes. This depends on "[PATCH 00/60] pinctrl: renesas: Share more pin group data"[1]. Changes compared to the BSP: - Share QSPI pin group data.
