[PATCH V2 1/5] pinctrl: r7s72100: add riic groups

[Wolfram Sang]

From: Wolfram Sang <wsa at sang-engineering.com>

Tested RIIC2 on a genmai board. Other riic groups are untested but seem
trivial enough to be added.

V2: keep sorting alphabetical

Note: With the current PFC driver as posted by Magnus, it needs another patch
to work. Yet, I think this is a seperate PFC issue which needs to be sorted out
seperately and shouldn't affect these declarations. I'll add the needed patch
as a response to this mail.
