[PATCH 4.4.y-cip 21/30] pinctrl: sh-pfc: r8a7790: Add SCIF_CLK support


Biju Das <biju.das.jz@...>
 

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

commit 53ec9ccd1c62b644d81674e013b1800dd88ec92b upstream.

Add pins, groups, and a function for SCIF_CLK, which is the external
clock source for the Baud Rate Generator for External Clock (BRG) on
(H)SCIF.
