i2c: Set i2c pinctrl recovery info from it's device pinctrl

Browse Source 
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.
