[PATCH 04/04] pinctrl: sh-pfc: r8a7794: Break out ODDF from sync

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

From: Magnus Damm <damm+renesas@opensource.se>

Break out the r8a7794 DU ODDF (EXDISP/EXODDF/EXDE) signal
from the sync group into a separate unit. This makes the
sync group fit with the r8a7794 ALT board that only uses
HSYNC and VSYNC signals.

This makes the r8a7794 PFC similar to the existing r8a7791
PFC DU implementation that also groups together HSYNC and
VSYNC without ODDF.

The groups "du0_oddf" and "du1_oddf" are added and the
"du0_sync" and "du1_sync" groups are modified.
