[PATCH] omap: i2c: Add calls for pinctrl state select

[pascal.huerst-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org]

From: Pascal Huerst <pascal.huerst-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>

This adds calls to pinctrl subsystem in order to switch pin states
on suspend/resume if you provide a "sleep" state in DT.
