Subject: [PATCH 3.16 51/99] pinctrl: sh-pfc: sh7264: Fix PFCR3 and PFCR0
 register configuration

3.16.65-rc1 review patch.  If anyone has any objections, please let me know.

------------------

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

commit 1b99d0c80bbe1810572c2cb77b90f67886adfa8d upstream.

The Port F Control Register 3 (PFCR3) contains only a single field.
However, counting from left to right, it is the fourth field, not the
first field.
Insert the missing dummy configuration values (3 fields of 16 values) to
fix this.

The descriptor for the Port F Control Register 0 (PFCR0) lacks the
description for the 4th field (PF0 Mode, PF0MD[2:0]).
Add the missing configuration values to fix this.
