[PATCH 03/05 v2] pinctrl: sh-pfc: r7s72100 single pin macros

[Magnus Damm]

From: Magnus Damm <damm@xxxxxxxxxxxxx>

Introduce macros that allow description of one pin per line.
Compared to the other ways of doing this, using this style
we can compresses the description of each pin from 9 to 1 line.

Signed-off-by: Magnus Damm <damm@xxxxxxxxxxxxx>

 This patch uses RZ_PMX_GROUP and RZ_GROUPS, thanks Laurent!
