Intel Merrifield provides a DR support via PMIC which has its own
extcon driver.
Add a property string to link to that driver.

[ Upstream commit f058764d19000d98aef72010468db1f69faf9fa0 ]
A call to 'regulator_get()' is hidden in 'twl6030_usb_ldo_init()'. A
corresponding put must be performed in the error handling path, as
already done in the remove function.
While at it, also move a 'free_irq()' call in the error handling path in
order to be consistent.
