[PATCH 03/04] pinctrl: sh-pfc: r8a7794: Add missing dot clock signals

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

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

Add missing r8a7794 DU dot clock output signals and in
particular the DU1_DOTCLKOUT0 signal on GP4_25 which is
needed by DU1 on the r8a7794 ALT board.

The groups "du0_clk_out" and "du1_clk_out" are replaced by
"du0_dotclkout0", "du0_dotclkout1", "du1_dotclkout0" and
"du1_dotclkout1".
