[PATCH 04/05 v2] pinctrl: sh-pfc: r7s72100 SCIF support

[Magnus Damm <magnus.damm@gmail.com>]

From: Magnus Damm <damm@opensource.se>

Add support for SCIF functions SCK, TXD, RXD, CTS and RTS to the
r7s72100 PINCTRL code. There are two possible pins that can be used
for TXD (Port 3 Pin 0 Function 6 and Port 3 Pin 1 Function 4) and
because of that are pins broken out into separate functions.
