Currently the i2c subsystem rely on the controller device tree to
initialize the pinctrl recovery information, part of the drivers does
not set this field (rinfo->pinctrl), for example i2c DesignWare driver.
The pins information is saved part of the device structure before probe
and it's done on pinctrl_bind_pins().
Make the i2c init recovery to get the device pins if it's not
initialized by the driver from the device pins.
