pinctrl: sh-pfc: only use dummy states for non-DT platforms
If pinctrl_provide_dummies() is used unconditionally, then the dummy state will be used even on DT platforms when the "init" state was intentionally left out. Instead of "default", the dummy "init" state will then be used during probe. Thus, when probing an I2C controller on cold boot, communication triggered by bus notifiers broke because the pins were not initialized. Do it like OMAP2: use the dummy state only for non-DT platforms.
