Subject[PATCH 01/03] pinctrl: sh-pfc: r7s72100 SCIF2 port3 support
From: Magnus Damm <damm@opensource.se>

Add support for SCIF2 port3 pin functions SCK, TXD and RXD 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 the data pins broken out in separate TXD and RXD.

This format is similar to other sh-pfc code, but a following patch
converts this to less verbose and less readable code.
