regulator: bq257xx: Make OTG enable GPIO really optional 



The bindings describe the OTG enable GPIO as optional, but the driver
gets upset if it's not provided in the device tree.

Make the driver accept the absence of the GPIO, and just use register
writes to handle OTG mode in that case, skipping the error message for
-ENOENT.
