pinctrl: sh-pfc: r8a7795: Fix SCIF_CLK_{A,B} pin's MOD_SEL assignment to MOD_SEL1 bit10

This patch fixes SCIF_CLK_{A,B} pin's MOD_SEL assignment from MOD_SEL1
bit11 to MOD_SEL1 bit10.

This is a correction to the incorrect implementation of IPSR register
pin assignment for R8A7795 ES2.0 SoC specification of R-Car Gen3 Hardware
User's Manual Rev.0.53E or later.
