devicetree: Fix improper use of chip_operations

Auto-discoverable PCI devices do not require field .enable_dev
of chip_operations to be set. They are matched with PCI drivers
by the use of PCI vendor and device ID fields.

The name given for the chip_operations struct must match the
pathname the way it is present in the devicetree.cb files. If
there was no match, util/sconfig would currently choose to
use the empty weak declaration it creates in static.c file.
