pinctrl: renesas: r8a779g0: Add missing SCIF_CLK2 pin group/function

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

pinctrl: renesas: Annotate sentinels in tables

It does not make sense to have a comma after a sentinel, as any new
elements must be added before the sentinel. Hence drop all such commas.

Add comments to clarify the purpose of the empty elements.
