pinctrl: sh-pfc: r8a7795: Add SCIF_CLK support
Add pins, groups, and a function for SCIF_CLK on R-Car H3 ES2.0. SCIF_CLK is the external clock source for the Baud Rate Generator for External Clock (BRG) on (H)SCIF serial ports. Extracted from a big patch in the BSP by Takeshi Kihara. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Cc: Takeshi Kihara <takeshi.kihara.df@renesas.com>
