Wolfram Sang 0129801be4 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.
