Subject: [PATCH 6.1 260/451] pinctrl: renesas: r8a779g0: Add missing SCIF_CLK2 pin group/function

From: Geert Uytterhoeven <geert+renesas@...der.be>

[ Upstream commit 68540257cdf1d07ff8a649aa94c21c5804bbb9b0 ]

R-Car V4H actually has two SCIF_CLK pins.
The second pin provides the SCIF_CLK signal for HSCIF2 and SCIF4.

Fixes: 050442ae4c74f830 ("pinctrl: renesas: r8a779g0: Add pins, groups and functions")
