usb: ulpi: set mod_name in driver registration
The driver core only creates the sysfs "module" symlink for a built-in
driver when its struct device_driver has mod_name set (see
module_add_driver()). This driver left mod_name unset, so its built-in
form had no such symlink.
Set mod_name to KBUILD_MODNAME during driver registration. Built-in
drivers now gain the symlink, while loadable modules are unaffected.
